Good to hear! Note that if the UDP connection is ended in other ways this will fail, but I will provide an updated solution on Monday that should handle this.

My pleasure anyway!

Hi, Bard!

We have found the bug, and I have a (temporary) solution ready. The issue is related to non-graceful shutdown of the UDP thread(in the middle of a recvfrom(...)), leading to problems with the sockets used by the at_cmd library.

Please replace <slm_root_directory>/src/tcpip_proxy/slm_at_udp_proxy.c with the following file: devzone.nordicsemi.com/.../5700.slm_5F00_at_5F00_udp_5F00_proxy.c

Then replace <ncs_root_directory>/zephyr/subsys/net/lib/sockets/CMakeLists.txt with the following: devzone.nordicsemi.com/.../7446.CMakeLists.txt

This should enable the normal "AT+" functions to continue working.

Hope this works for you and please reach out if you need further assistance. I will also notify you when this bug is "officially" fixed.

Best regards,
Carl Richard

Hello, Bard!

My apologies for the lack of support on this case. I have started a process with the developers on hunting down the bug, and I'm looking at possible workarounds myself. It seems to be related to the UDP-commands locking up at_cmd.h, but that was probably clear to you aswell.

I was also just informed that it could be an issue with your development kit version, so Magnus should have arrangef for a new one to be shipped to you.

Will come back with more updates shortly.

Best regards and thank you for the patience,
Carl Richard

Hi, Bard!

I can reproduce the issue here, but I'm not sure why it's happening, I have taken it up internally and will come back to you.

Best regards,
Carl Richard
