I followed the instructions set out to connect between 2 separate E32 - Raspberry Pi setups using the kiss.sh script and AX25 tools, to no avail alas...... 8-(

Using 2 x EBYTE E32 (868T20D)
Tried with Pi Zero, Pi 3A, Pi 3B and Pi 4

Tried with both a USB - TTL adapter and direct connection to the UART pins on the Pi's
(amended the kiss.sh script to ttyS0 and ttyUSB0 appropriately)

Swapped the TX and RX pins in both the USB and direct UART pin connection to check they were set OK

Ran "sudo axlisten" after starting "sudo ./kiss.sh" and ran both ping and traceroute first to the devoices own local IP (10.0.0.1 or 10.0.0.2), all OK then attempted to do this between both devices.

Saw attempts to connect through the AX0 port via "axlisten" but bombing out with no responses.

Not sure if I have missed anything, any ideas of next steps?

Thanks

I'm currently trying to modify tx_beacon.py to accept a custom payload.

If the payload length is set for more characters than are typed into the message the extra characters are nonsense.
Eg; If the payload length is set to 100 and I type in "HelloWorld!" I get this:
HelloWorld!:/▒▒g▒Ƴ▒s'▒4▒*▒▒}▒▒▒E▒▒^▒▒▒v▒▒▒▒▒>_▒џ▒t▒X▒GKԿz▒{▒▒▒▒▒xȅR▒▒▒▒U▒▒▒▒_▒▒gc>▒▒▒▒▒

Does this support LoRa modules connected over SPI?

Thanks!

Would it be possible to create a setup to chat between two arduino or two nodemcu esp8266 or just two android phones connect with an OTG cable and serial port to usb adapter and a lora E32-DTU to communicate between the two without the need for servers? It works with my two E32-DTU modules connected with an OTG cable on android but I have to use a terminal and it's not chat friendly! The modules I am talking about here are E32-DTU lora at 1 watt and which already have an RS232 and RS485 output and its own power supply! I would be very happy to use these modules to discuss, I would like to know if my ideas are feasible, good or simply impossible! thank you in advance and sorry for my bad english I speak in french 😉
(And even Android with OTG cable and RS232 to usb adapter to speak with a user on windows or linux! I know it's 100% possible via a terminal but I'm looking more for an application like you present it in your github)

If anyone knows, please get in touch!

This project seems to share some aims with

What happened to all the code?

When writing a large paragraph into the chat, words are cut off and sent to the next line. See the screenshot on the main page for an example.

Hello !
First congratulation for the idea. Using cheap LoRa hardware for AX.25 and later for mesh network.
There is also an other project https://github.com/chazapis/eoax unfortunately it's seems abandoned.
There is also an closed source and proprietary solution called GoTenna. What you are trying here it's same thing but open source.
Since there is no future request section I will write here.
An LoRa + Bluetooth will allow also communications with mobiles (Android/IoS) like GoTenna, but much cheaper.
Once the layer 3 is functional it can be used with many low bandwidth chat software.
In my case I intend to use it with www.briarproject.org they are also looking for long range transports.

The output when receiving a message is like this:
{'cad_detected': 0, 'fhss_change_ch': 0, 'cad_done': 0, 'crc_error': 0, 'tx_done': 0, 'valid_header': 1, 'rx_timeout': 0, 'rx_done': 1}
['0x48', '0x65', '0x6c', '0x6c', '0x6f', '0x20', '0x57', '0x6f', '0x72', '0x6c', '0x64' ,'0x21']

Ideally it would be output like this:

Hello World!

Please check the new file combine_rx_tx.py to see my attempt.
I get this error when I run it:

Enter a message >>
ttt
Traceback (most recent call last):
  File "combine.py", line 118, in <module>
    lora.send()
  File "combine.py", line 86, in send
    handle_input(input)
NameError: global name 'handle_input' is not defined

I apologize beforehand for writing here, but it did not allow me to write in requests. I want to tell you that this project is amazing. I just wonder if it would be possible to create a bluetooth modem for chatting through the phones from this board? Android phone wiill be only pair with board through bluetooth and send packet over lora to next devices?

I need to find a way to loop the send and receive modes (line 113 to 119)
So it will work like this:

• Chat device starts in receive mode
• Press ctrl+c and then you can type a message and press enter to send
• After send done goes back to receive mode

That process needs to keep looping over.
