GSM Manager No Modem found

[Eivy1987]

Hi together,
I really like your project. Thank you already

I organized with your documentation link, a Lily Go Board on AliExpress (EU Version).
After arrival, I went after your documentation video to configure the device via USB-C and Windows (worked all like in your video).
The device after configuration is connected to Wi-Fi, and it's pingable as well. Sim Card is inside. Under logs and & console

I have the following issue:

Googling this issue is leading to no results, and I really don't know how to solve that. Is there an additional step which is missing?
My board has also two USB connections, once USB-C(which I configured the device) and another USB Micro (maybe for the Modem)

Attached are two pictures of how everything is connected.

I hope you can help me to get it running (That modem gets found).
PS: I wanted to buy your configured device, but it was not available:-)

Hi, currently firmware support only older version of the board which used different pins for serial port. You can change the serial pins config, so that they match your board in https://github.com/ParetoSecurity/sms-slack-v3/blob/main/platformio.ini and then compile and flash it using platformio.

-   DSMS_RX='16'
-   DSMS_TX='17'
+   DSMS_RX='26'
+   DSMS_TX='27'

If the change works, please report back so that we can add it to the config.

Hi, I had the same issue as Eivy1987.
I cloned the repo and made those pin-changes. Flashing with platformio was not possible, so I did that manually with the esphomeflasher. After flashing it starts up correctly and logs the signal-strength and IMEI. But I still receive no SMS which I sent from my mobile to it.

Furthermore I see that it should log the operator-name as well but it doesn't.
gsmAt.GetOperatorName(ops); ESP_LOGI(TAG, "Operator: %s", ops.c_str());
Just the two lines for signal and IMEI repeating.

Any hints how I can resolve this? :)

[godstone]

After flashing it again with the new rx, tx numbers, it's back to square one and repeating "No Modem found"

[dz0ny]

Make sure you don't have SIM locked. Also which variant of modem do you have? You can try disabling LTE mode (https://github.com/ParetoSecurity/sms-slack-v3/blob/main/src/GSMManager.cpp#L48), because it might not be supported on specific band. Whole LTE is such a mess and these modules heavily depend on tower and provider.

[godstone]

SIM is unlocked :)
I've got the v1.1 2022-2-28 XY--A7670E
I've flashed it now with disabled LTE. It looks a bit different but stillnot completely right. 😄 Also enabled the DEBUG mode

Flashed it again and 5 test-message came into slack. After that it goes back into that loop above an no new messages come in.

Looks like it's not supported by your provider. If you have other SIMs try them to see if they allow registration.
