How do I change the config one it's running? Browsing to the IP doesn't seem to work

platform.io will automatically download env and needed libraries, consider to move project on platform.io

My 3 devices did go to zero 9 hours ago (zsolo and port 6056).
I tried to reset or reboot my router with no luck. Change to ckpool fix the problem.
I see that in zsolo web there isn't mention to the very low hash port (dissapear) and only normal diff (>500)
Using 6057 doesn't works anymore.
Back to ckpool before nerdpool will go online. ;)

@econoalchemist has a pool:

[Taken from recent Spotify pod256 pod cast description]

Pick any Lincoin URL:

a)  stratum+tcp://NA.lincoin.com:3333

b)  stratum+tcp://EU.lincoin.com:3333

c) stratum+tcp://LatAm.lincoin.com:3333

d) stratum+tcp://CIS.lincoin.com:3333

e) stratum+tcp://Asia.lincoin.com:3333

f) stratum+tcp://OC.lincoin.com:3333

g) stratum+tcp://Africa.lincoin.com:3333

Then use "pod256.YourAlias" as the worker name.

I tried to use 'NA.lincoin.com' and port '3333' but 'shares' counter on NerdMinder does not increase. hash rate stays at 0.00.

Is any special setup required in order to connect to a mining pool or does the mining pool need to support a specific connection?

Hi! Cool project!
When I connect to wifi it reboots multiple time and it connects succesfully to the wifi but ends up disconnected and back in AP mode. When I login wifimanager says authentication failure.

Tried to find solutions in wifimanager github but no real success for a solution, although connection issues seem to be prevalent in wifimanager:
tzapu/WiFiManager#1067

Hello,

I just started running nerd miner, it is a great project.
I have try get BTC address from my trezor and put in a config. firstly i run with ckpool for 2 hours and when I check on the address https://solo.ckpool.org/users/MYBTCADDRESS and it show the page not found then I decided to reset the config and try with zsolo pool and it was run for 10 hours but still no hash rate show up on the page https://zsolo.bid/en/user/btc?address=MYBTCADDRESS

Not sure this is normal or a bug on the miner.

I have a own BTC Node and setup a pool on it with the mining diff 0.00001.

The Nerdminer is not able to find share with this diff. I find that a bit strange.
Now I tried a CPU miner on my PC that has only one thread (11-18 KH/s) and I find 5-10 shares per second with it. My NerdMiner has 21 KH/s.

On the Global Stats screen there's a section which says "halving". I believe this metric actually refers to the blocks until the next difficulty adjustment.

HI,
i see there is another firmware that deals with Battery. thanks.
i tried it right away and get the same behavior as before however :

If a battery is plugged in and you disconnect the USB power source to use the miner on the go ...the screen goes black.
when you plug it in again to an usb power source, after some time, you see that it has gone on mining during the "black out" . time, shares, Millions hashes .. have continued and gone up. Great.
so it is working and may be that shouldn't be an issue ?

Is my 3.7 v 1000mAh battery too weak somehow ? it fits the 3.4v ESP need ...
can you recommend some or post the one you used that obviously works fine including the display and can fit within the miner's box ?

Thanks.

Love this project, and my little contribution is following

I've just quick and dirty created little PCB to be able to fit into T-Display-S3 as is

@BitMaker-hub Once I got it, I'll do a PR to implement this in code (and show CPU Temp on display), but if you want to add this feature before, of course you can :-)

These boards are untested but should works without any issue

R1 10K 0805
D1 1N4148
Q1 BSS138 SOT-23

You can order 3 boards (RAW PCB) for less than $2 shipping included at OSHPARK

Have fun

Hi

My NerdMiner crashes quite often. The longest runtime I have seen so far was a bit more than an hour. But it could also happen after a few minutes. This is what I see on the serial console.

Any idea what is causing that?

Regards

I tried ckpool and zsolo and it doesn't show it's hasing but it does show it's working on the screen at 20+KH/s

I reloaded the new bin files today as well.

I apologize as I am a bit new to this platform and still working through some of the tooling involved, but I am pausing here to make a report that might help others with testing. I have successfully connected to a pool and started mining using pool solo.ckpool.org. Great work NerdMiner_V2 team.

I ran into this issue trying to determine what was going on when there was no handshake happening with the upstream pool and needed to change the configuration.

• For a configured NerdMiner, disabling the specified access point helps put the NerdMiner into NerdMinerAP configuration mode after some time. I read else where holding the top button 5 seconds might do the trick, but disabling the access point helped in my situation when button access was an issue.

• Connect to the webapp at http://192.168.4.1 and change the ssid and password values and submit. NOTE: While the ssid and password are the only values offered from the webapp and the webapp is the only presentation relevant to this issue, for fun I did try variations using curl to get at the configuration values i.e.

curl --location --request POST 'http://192.168.4.1/wifisave' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 's=myssid' \
--data-urlencode 'p=myssidPassWord' \
--data-urlencode 'Poolurl=btc.zsolo.bid ' \
--data-urlencode 'Poolport=6057' \
--data-urlencode 'btcAddress=bcxyzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz6d'

• The result is the ssid is not changed and the NerdMiner connects to the previously configured ssid.

• The only way I found to change the mining configuration is erase the flash AND reflash the firmware.

I hooked up the serial console and here is what I observed when using the NerdMinerAP configuration mode and attempting to change the ssid from the webapp a couple times:

Hello !

Thank you for this amanzing little miner and all your work.

I have a problem : when I load the firmware with the binaries from the src/bin folder, i have the following error :

This is weird because the miner seems to work perfectly.

How can I verify if there are something wrong ?

I've seen a few people on twitter and telegram, some of whom have 4+ nerdminers.
Wouldn't an OTA feature be useful specifically for these people?

Hey everyone, just a small question, can I use multiple devices with same user id (btc address) on the same pool? For example a NerdMiner and my old laptop, can they both use same btc address?

Does this also works with the 1.14 inch version instead of 1.9 inch display?

I tried but I got no image on display after flashing firmware.

Hi! the templates keep running up, but there the shares and hashes keep at 0. Tried different power sources, usb cables and system resets. The receive address is correct. Have run it all day, but the hashing is still at 0. Anything else I could test?

Not an issue, but a question. Don't know where else to place it:

Can someone explain this that is in the readme? What does it mean it is not seen by the mining pools?

IMPORTANT Miner is not seen by pools due to its low share difficulty. You can check miner work seeing logs via UART or mainly setting up your own pool with a low difficulty rate as 1e-9

Can someone explain if there will come a mining pool just for nerdminers and why that would be better?

I do own one ESP32-S3 Box and one WT32-SC01 Plus. Both boards are S3 compatible, but do have other display resolutions. It would be nice, to support also other boards for this.

If wanted, I could create PRs for that.

hi,
since the ESP allows it. i plugged a battery on it.

i used one like the one on the photo on another ESP for another project ( the very good PoS ).

the idea is sometimes, for show or demo purposes or for fun on a desk to have the miner working without any wire. looks nicer and .. mysterious !
not for a long time but an hour or 2 would be nice.

the ESP is 3,7v so it could work on the 3.4v ... and it .. almot does.
when unplugged with the battery in it it goes on mining allright i think. but the screen stays black. you recover it when plugging again and see that the process is still on and running. ( looks like it anyway)

so it is close.
what is it missing ? some mA ? or is there a hardware safety measure ?
Could some code arrange that ? : test if battery on and make it work at a "slower" hashrate for example ?
or add a little electronic ? ( i saw an addon with a resistor to be able to tune the vent speed...)

It looks to me like a nice possible upgrade
i go from afar but i am quite willing to help work on it if you and/or other people think it is interesting.

but you haven't proposed or spoken about it, i suppose there is a good reason for that...

this is more a proposal with an issue than a real issue though. let me know if this should be posted elsewhere

I do not see a possibility to configure the BTC address after a reset.

the miner works so far. If USB-C is on the right, the top button is totally reset. It works. I couldn't understand the function of turning the display with a double click and display off. Version 1.4

Hi

My NerdMiner crashes quite often. The longest runtime I have seen so far was a bit more than an hour. But it could also happen after a few minutes. This is what I see on the serial console.

Disconnected and reconnected to power, but screen is blank and lights are not blinking. Is it issue with power cable ?

Instead of having the display always on, it would be nice if there was an option to have it off by default and switch it on for some seconds when a button is pressed.

Is it possible to change the Uptime in "days - hours - minutes" if it reaches above 24h or in general?

Hi.
Is this possible to be run in other versions of ESP32 such as ESP32 DevKitC-32E, which is based in the following iiem:
https://www.espressif.com/en/products/devkits/esp32-devkitc
and based on this part:
https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32e_esp32-wroom-32ue_datasheet_en.pdf

After running for a few hours, the hash rate goes to zero. That issues usually takes 24 hours to happen.

I had a device that I flashed successfully, but when I tried connecting to the access point it would not connect and show a 'password incorrect' message on my phone. Also the QR did not work. Tried flashing multiple times but the problem persisted. 3 other devices did not have this issue at all.

The solution was to do an "Erase flash" first in the ESP Tool flasher, and then load the firmware again. After that the issue was fixed. Putting it here for others, as a pull request for one line in the readme seemed a bit of overkill. ;)

cheers,

Hello somebody know how to make 180° screen rotation to use connection link on the left ?

Would be nice if there is a debug screen we can access using button press so that if anything isn't working correctly we can check it for notifications/cause. This way we can report errors easier.

The debug screen would only keep the most recent 5 notifications and all older notifications will be pruned/removed. This would prevent log bloat/overfill.

Can I use other Displays like a TFT 1,8" ST7735S?

Hi BitMaker,

Is there a way to view my miner (via Braiins Dashboard on web/mobile app) after I connect to the Braiins slush pool?

Thank you.

Using firmware '0x10000_firmware.bin', the only button option that works for me is:
Hold 5 seconds > top right button to reset the configurations and reboot your NerdMiner.

Device: LilyGO TTGO T-Display-S3 ESP32-S3 - met 1.9 inch TFT Display

TOP BUTTON

• One click > change screen.
• Hold 5 seconds > top right button to reset the configurations and reboot your NerdMiner.
• Hold and power up > enter configuration mode and edit current config via Wifi. You could change your settings or verify them.

BOTTOM BUTTON

• One Click > turn the screen off and on again
• Double click > change orientation (default is USB-C to the right)

When wifi is configured but detecting wifi on startup fails, autoconnect hangs and start a new AP.
At screen appears 0.00 Hashrate

hey how does one flash the firmware, or compile first and then flash the firmware I guess. Is there a blogpost or tutorial beyond "Load the firmware with the binaries from the src/bin folder.
Plug your board and select each file from src/bin with its address"
Cause thats where I am stuck. How do I load the firmware from either the src folder or bin folder. Or from both folders?

I have upgraded all 3 of my nerdminers to release v1.4. (firmware bin only, as that was the only file updated).

I have one miner pointed to each of the following pools:

• CK pool
• braiins pool
• zSolo pool

All three pools / miners were relatively stable prior to the upgrade. They would reset maybe every 24hrs +/-.

Now I am seeing the braiins Nerdminer rebooting itself every 8-10mins approx.

The other two miners appear to work fine so far. I will continue to run them to check stability.

L hash rate del nerd miner si blocca dopo un po' di ore e rimane a 0...va spento e riacceso perché riparta

Hello,

When trying to flash the firmware, I am getting the message: "Error: CryptoJS is not defined" and the firmware is not flashed.

Any thoughts on how to solve this?

I was able to configure the miner but once it went through the setup, the main screen just shows the count for how long the device has been on. All other items being tracked on the screen are at zero.

What to do when
Bloc templates and 16bits shares and hashes stay on 0?
Already did a reboot.
Online time seems to work.

Hi, after about 2-4 hours, the miner is currently leaving my WLAN. No new blocks are then requested and the hash rate goes to zero. Everything else seems to continue to work. At the moment I can't see why it should be. Version is the latest 1.4
Edit: now i have a uptime from 13h, I hope he lasts a while longer.

Nella configurazione del mio nerd miner ho messo il mio indirizzo btc...ma se cerco tra i minatori il mio indirizzo non esiste

After 12 hours I have many 16bit shares, but still 0 32bit shares. What is likely normal to get a 32bit share of the amount of 16bit shares, or in time?
I get a feeling that the issue about parsing JSON, mentioned here, could be a problem why it doesn't get 32bit shares? Or am I wrong?
