Hi,

Thank you for additional information.

Can you test if the same problem exists in NCS v2.8.0?

Best regards,

Data mode is exited in one of two ways. I can simply just wait until the data mode timeout is trigger. In this case we receive the payload and the first character(s) of the termination string.

Alternatively datamode may be exited by sending the termination string again, which is what I did in the procedure listed.

The same behavior can be described when "12345hel" is sent as well, to exit data mode in this case I either wait for the datamode timeout or send an additional termination string.

I am currently moving forward with my proposed solution, so I unfortunately do not have a full log of the AT commands and their responses. I suspect following my listed procedure would be reproduce the same behavior.

Hi Ben,

Thank you for reporting this potential bug and providing possible solution.

[quote user=""] if the last character of the payload is the first character of the termination string, the device will not exit data mode.[/quote]

How do you exit data mode in this case?
Were you not able to exit data mode also in the other described situation when you sent "12345hel"?

[quote user=""]

I performed the following steps to recreate this (Note: this assumes the termination string is hello)

Connect the device to a serial terminal
Turn on device modem with AT+CFUN=1
Connect to MQTT broker using AT#XMQTTCONN=<MQTT credentials>
Set datamode timeout to 20 seconds using AT#XDATACTRL=20000 (this is just so I have time to send my messages)
Enter data mode using AT#XMQTTPUB=<MQTT pub message>
Send 12345h
Send hello\r\n
In this case data mode does not exit, so I must send hello\r\n again.
I check the what is sent over MQTT, and see that it is 12345hhello

Can you provide full log containing all used AT commands and their responses?
