AT_MODE_NO_SUPPORT when trying to send a message in P2P

[adrianza (Adrian Zarnescu)]

Hello,

I’m trying to send a message in P2P, but the response is AT_MODE_NO_SUPPORT.
I don’t understand what I’m doing wrong.
This is the log:

When I use AT+PSEND instead of AT+SEND, the response is:

19:19:38.703 -> AT+P2P=?

Welcome to RAK forum @adrianza ,

I did test about it using the latest firmware and I didn’t see that issue.

My suggestion is maybe perform a full chip erase first using STM32CubeIDE then upload the rui3 v4.0.5 then test again using the same configuration.

Hi @carlrowan ,
Thank you for your answer!
I did what you suggest and works great now.
