No response to AT

[slight]

I got up to this stage while trying to evaluate the module...

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf91_dk_gsg%2FUG%2Fnrf91_DK_gsg%2Fintro.html

There is no response to AT+CFUN=4 (or even AT). I successfully updated the modem and application FW to the latest prior to this. I have tried switching the board on/off, etc. without success.

Hi,

What application are you running on the nRF91?

What are you using to send the AT comand?

Do you get any log from the device?

Best regards,

Didrik

I'm following the getting started guide for the dev kit. Terminal app in nRF Connect v3.7.1.

I programmed the modem using the procedure in the Getting Started guide (mfw_nrf9160_1.3.0.zip). I note there is an extra _ character in this file versus what the guide says.

In any case, I tried programming it again. It said it verified successfully, but still no response to AT commands.

Do you still get the same errors in the log?

[1;31m<err> at_cmd: Failed to open AT socket (err:-117)

[1;31m<err> at_cmd: Failed to send AT command (err:9)

[slight]

Yes, same errors

Had a call with David Martin. Turns out the kit I ordered was old stock (rev 0.8.3), so that is probably why I am having these issues.

Yes, that would probably explain it.

Modem FW v1.3.0 does not support the engineering revisions. However, it should work if you use mfw v1.2.3.
