Modem AT port freezes if I send empty line

[BitManu]

Greetings,

If I send empty line (CR or CRLF) to the modem AT port, modem freezes.

Firmware version: 1.2.1

AT%SHORTSWVER
%SHORTSWVER: nrf9160_1.2.1
OK

User application (log):

Modem never answers after empty line.

I am using teraterm to test this.

Hi,

This is a known limitation in the at_cmd libarary.

A PR with a fix has been merged, so this problem should be solved in the next version of NCS: https://github.com/nrfconnect/sdk-nrf/pull/3033

Best regards,

Didrik

Thanks Didrik
What is the schedule of the next NCS version?

 I can not comment on that here on DevZone. Instead, you should direct this question to your Regional Sales Manager.

If you do not know how to contact your RSM, send me a private message with your location, and I will provide the contact details.
