Support for 4G Modem with USB interface (IDFGH-8221) about esp-protocols HOT 31 CLOSED

I've the same question. Please let me know if possible @team

from esp-protocols.

Hi Team,

Any update for this request ?

from esp-protocols.

The console example supports USB interface, please check

https://github.com/espressif/esp-protocols/tree/master/components/esp_modem/examples/modem_console#usb-dte-support

It's just a sub-component to this example at this moment. We're working on making this an independent component, deployable separately in the component manager.

from esp-protocols.

@david-cermak thanks for the update. How long should it take for the independent component? As we are moving with production code. So we should wait or move forward with the sub-component?

from esp-protocols.

@abhi-ratnman @rmshub Could you please take a look at #89 ? And let me know whether this changes fit your needs?

Early version of USB_DTE plugin is uploaded here, and source code is under review espressif/idf-extra-components#92. I'd appreciate any ideas!

I checked the component and example. Is there support for other modules? The code is for BG96. How to add support for SIM7672? @david-cermak @tore-espressif

from esp-protocols.

@abhi-ratnman you need to find VID and PID of the device. You can use USB Device Tree Viewer on windows or lsusb on linux to find it out.

Then, you need to know interface number that is used for AT commands. You should find that in SIM7672 datasheet, or you can find it by trial-and-error, starting from 0.

then you can use these values to initialize USB-DTE

struct esp_modem_usb_term_config usb_config = ESP_MODEM_DEFAULT_USB_CONFIG(vid, pid, intf_num);
const esp_modem_dte_config_t dte_config = ESP_MODEM_DTE_DEFAULT_USB_CONFIG(usb_config);  
ESP_LOGI(TAG, "Waiting for USB device connection...");
auto dte = create_usb_dte(&dte_config);

from esp-protocols.

@tore-espressif @david-cermak

struct esp_modem_usb_term_config usb_config = ESP_MODEM_DEFAULT_USB_CONFIG(0x1e0e, 0x9011);

    usb_config.interface_idx = 3;

    const esp_modem_dte_config_t dte_config = ESP_MODEM_DTE_DEFAULT_USB_CONFIG(usb_config);  

    ESP_LOGI(TAG, "Waiting for USB device connection...");

    auto dte = create_usb_dte(&dte_config);

    std::unique_ptr<DCE> dce = create_SIM7600_dce(&dce_config, dte, esp_netif);
    

Used the above config. Still the code is stuck in waiting for USB Device connection. The interface number in the sheet is 1 but tried from 0-3 still it is not getting connected.

The hardware connection is good as i have tested the same connection with https://github.com/espressif/esp-iot-solution/tree/usb/add_usb_solutions/examples/usb/host/usb_cdc_4g_module this code. And it gets connection (in menuconfig selected sim7600 as the board.)

@abhi-ratnman could you share full device and configuration descriptors? I will take a look

from esp-protocols.

@abhi-ratnman In case you missed it:

from esp-protocols.

@tore-espressif which device and configuration descriptors are required?

Also the reset part is taken care of and i try restarting it manually in case not done automatically. I've tested the usb CDC code like that only and it works fine.

from esp-protocols.

which device and configuration descriptors are required?

Ideally all of them :) @abhi-ratnman

To get your USB descriptors you can do the following:

1. Connect (and turn on) the modem to host PC USB port
2. Then, depending on your platform:
   2a. Windows: Install USB Device Tree Viewer, find the modem in list of connected USB device and attach all information here
   2b. Linux: run lsusb --verbose and attach the output here

from esp-protocols.

Please find the above attached file @tore-espressif

from esp-protocols.

Hi @tore-espressif any update? Do u want any more information?

from esp-protocols.

Please find the above attached file @tore-espressif

please use usb_config.interface_idx = 5;, the rest of your configuration seems correct.

from esp-protocols.

@tore-espressif checked usb_config.interface_idx = 5; as well the code is still stuck at the same place. Is there any way to change the USB in and out address as per mentioned in this issue espressif/esp-iot-solution#121 (comment)

Also a strange thing is happening, whenever ESP try to connect USB the module gets restart. Photo of the connection is as below.

from esp-protocols.

@abhi-ratnman if your code gets stuck on device open, it indicates a different problem, could you please share your log?

Is there any way to change the USB in and out address as per mentioned in this issue espressif/esp-iot-solution#121 (comment)

USB endpoint addresses are bound into USB interfaces. Interface 5 contains endpoints 0x81 and 0x0A.
Endpoints mentioned in the linked comment 0x86 and 0x0F correspond to interface 4.
you can find the rest in the descriptors that you sent me.

I'll test in on HW as soon as I get my SIM7600 (~few days)

from esp-protocols.

@tore-espressif please find the below log output.

@tore-espressif @david-cermak any clue from the logs? Actually we are running late for the integration in our product. Hence I request if you can escalate the issue. Thanks :)

from esp-protocols.

Hi @abhi-ratnman , I just got mine SIMCom SIM7600E-H.
It is a little different from the module that you have. My PID, VID is: 0x1E0E:0x9001. I'm using endpoints 0x86 (IN) and 0x04 (OUT), which belong to interface no 3.

Please note that we updated the USB-DTE a little in past weeks, the changes might affect your usecase.
I'm working with:

• esp_modem version 0.1.23
• esp_modem_usb_dte version 1.0.0
• usb_host_cdc_acm version 1.0.3
• esp-idf master branch

Everything is working as expected with this initialization code:

struct esp_modem_usb_term_config usb_config = ESP_MODEM_DEFAULT_USB_CONFIG(0x1e0e, 0x09001, 3); // VID, PID and interface num of SIM7600E-H modem
const esp_modem_dte_config_t dte_config = ESP_MODEM_DTE_DEFAULT_USB_CONFIG(usb_config);  
ESP_LOGI(TAG, "Waiting for USB device connection...");
auto dte = create_usb_dte(&dte_config);
std::unique_ptr<DCE> dce = create_SIM7600_dce(&dce_config, dte, esp_netif);

Example output:

any clue from the logs?

From the logs I can see two things:

1. You aren't using the latest modem_console example. Try updating your local branch. Then configure the project for esp32s3, USB DTE and change only the configuration of USB-DTE
2. The USB library detects connection of a new device. But fails to open it. Updating to the latest code should fix your problem

from esp-protocols.

@tore-espressif @david-cermak

I updated to the latest esp-protocols something strange is happening even if i set target to esp32s3 the target is set to esp32c3.

Do not know the reason for that. Earlier when i would set target to esp32s3 it would set but in the latest update

Ah, I'm sorry about that, that;s a regression from #155. Please remove this line https://github.com/espressif/esp-protocols/blob/master/components/esp_modem/examples/modem_console/sdkconfig.defaults#L4
and rebuild from clean state (idf.py fullclean)

from esp-protocols.

@tore-espressif thanks for a prompt reply

Yes now it is solved but the earlier issue still remains in the latest code. As soon as USB is connected the SIM module gets powered off and it gets restart again and again.

While the same connection works fine with https://github.com/espressif/esp-iot-solution/tree/usb/add_usb_solutions/examples/usb/host/usb_cdc_4g_module this code. But the issue in this code is that I want to access CMUX but that is not implemented in the above example.

from esp-protocols.

@abhi-ratnman the unexpected resets might come from incorrect/insufficient power supply. Please check that your power supply has enough power for powering the SIM7672.

From the setup in the photo, I can see the USB VBUS signal is invalid too. ESP32-S3 devkit does NOT output +5V on the USB cable, so your VBUS line is not powered. Try connecting +5v on the VBUS line on SIM7672 USB connector.

@tore-espressif

For power supply a separate 5v 2A SMPS is used to power the SIM module which provides sufficient power to the module.

The same hardware connection work with the esp-iot-solution code as per the link provided. So if that would have been the issue it should occur there too?

the above image is a modified version of that code which only provides IP address

from esp-protocols.

@tore-espressif @david-cermak any update on this?

from esp-protocols.

Hi @abhi-ratnman , our support options are running short :( I have a little different modem than you have (although, the USB interface should be the same), with different firmware version. Unfortunately, I can't reproduce the issue.

Now, all we can do is (1)suggest a fix and (2)you have to try it and repeat until the issue is solved.

Have you tried connecting +5V on the modem's USB connector?

The same hardware connection work with the esp-iot-solution code as per the link provided. So if that would have been the issue it should occur there too?

I guess that the modem is not properly enumerated by the ESP32-S3 because it fails to reconnect after USB 2nd reset.
USB 2nd reset is a standard thing in enumeration process; every USB Host (Windows, Linux PCs) does it. But, the USB host implementation in the code that you're linking does not do it, simply because it is a pre-release version of Espressif's USB host.

from esp-protocols.

Hi @tore-espressif have tried with 5v usb supply still issue is the same

from esp-protocols.

HI @tore-espressif , I have a similar issue I am using the usb cdc_acm_host library to connect to a hl8548 from sierra wl. I am trying to use the cdc_acm_host_open() function to connect to it and send AT commands. The function works and i am able to connect to the endpoints but when i send some AT commands the module doesn't respond back. I am using the esp_idfV4.4.2.
we have been testing with the BG96 module and all works perfectly. could there be an issue with the fact that this module uses interface association ? I think the function I am suing supports it but I am not sure.

from esp-protocols.

@tore-espressif this are the deescriptors from the module I am using. I have tried to connect to all interfaces

Hello,
We have recently fixed several enumeration issues in esp-idf master. There are also few bugfixes in esp_modem_usb_dte v1.1.0. All the fixes are already implemented in esp_modem examples.
Could you please update your esp-idf and esp_modem and try again?
