BX310x: Crash on AT+KHTTPSPOST

Hi,

I am trying to use the HTTPSPOST feature of the BX3105 module (running 2.6.3 firmware) and I am having issues with it.

It crashes on execution of that command…

I connect to a HTTPS server and am able to use the HTTPSGET command on the same URI.

A sample communication suite:

> AT+SRWSTACFG="xxx","xxx",0
OK
> AT+SRWSTACON=1
OK
> AT+KHTTPSCFG=,server,443
+KHTTPSCFG: 1
OK
> AT+KHTTPSHEADER=1
OK
CONNECT
> Authorization: Token xxxxx
> Content-Type:text/plain
> +++
OK
> AT+KHTTPSPOST=1,/my_uri/
CONNECT
> *data_to_send*

Can you tell me what I am missing and what could be the cause of this problem?

Thank you,

Jay

I tried with and without " for the URI, with a single or two commas before the URI (in the example there were two commas), no success.
