nRF9160-AT_Client , LTE connect failure.

[JackyChen]

I flash v1.7.0 at_client and mfw-v1.3.0 into nrf9160-DK board, LTE works normally and the board can get the ip. (https://files.slack.com/files-pri/T0SBEQ7AR-F02J4REC8RX/nordic-lte.png)

But I flash the same firmware into mikrobus board of nrf9160 (https://www.mikroe.com/lte-iot-4-click) and use the same sim card, LTE doesn't work.(https://files.slack.com/files-pri/T0SBEQ7AR-F02HS8T4Q82/picture2.png) I test the antenna which I use on mikroboard, it is suitable for LTE.

I think newer software versions don't support the older hardware? or other reasons ?

Hi leadercxn,

Please check with the module manufacturer directly for this issue. The firmware has specific configurations for different hardware designs, so a firmware built for nrf9160DK should only run on nrf9160DK.

Best regards,
