ST67W611M1 connecting to WiFi AP with password including a comma is not working

Hi !

We're testing with the eval-boards NUCLEO-H7S3L8 + X-NUCLEO-67W61M1.
The software is the CLI project of the NUCLEO-H7S3L8.
At the bottom of this post you will find infos to the software versions.

There we're having an issue when we try to connect to an WiFi AP and the password includes a comma (',').
It looks the ST67W6X_Network_Driver is encoding and sending the AT-command correctly, but the NCP (ST67W611M1) response with ERROR.
So it seems to us it's an issue of the NCP firmware.


Via Shell/CLI we initiate the connection to the WiFI AP via the command wifi_sta_connect.

When we set the password at the AP to "pw123456" we can connect to the AP.
When we set the password at the AP to "pw123,56" we can not connect to the AP.


For debugging we followed the code in the ST67W6X_Network_Driver till function W61_AT_Common_SetExecute(..).

There the AT-command is sent and the response is received.
If the password is not including a comma, it is connecting to the WiFi AP successfully.
The communication of the AT-command and response looks like this:
    AT+CWJAP="Test_SSID","pw123456",,0
    OK
If the password includes a comma, it's not working, and an error occurs.
The communication of the AT-command and response looks like this:
    AT+CWJAP="Test_SSID","pw123,56",,0
    ERROR
The ST67W6X_Network_Driver logs the following:
    [ERROR] [469363] [shell_task] (w61_at_common.c:67) ParseOkErr Status : ERROR
    [ERROR] [469363] [shell_task] (main_app - CLI.c:527) [ERROR] in W6X_WiFi_Connect API

Please can you confirm this issue ?

Additionally we're currently selecting components for a new product and we wanted to use the ST67W61M1.
So we need to know if and when this problem will be resolved ?


Thank you !!

Seems that this is a not-uncommon issue; eg,

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
