AT command using stm32l496

[KBADA.1]

I recently bought "P-L496G-CELL02" and I would like to communicate in AT command with the module:

here is the message that appears:

Welcome to STM32-Cellular to Cloud (STM32-C2C)

AT commands terminal: connection to PC with USB-OTG FS is needed.

Modem is using eSIM.

The modem did not answer...

Please:

    - Connect The modem on STMod+ port

    - Install STM32 VCP drivers

    - Connect USB link to PC on USB-OTG FS

    - Set JP7 on U5V if no STLINK is plugged

    - Set SW1 to position "1" if no STLINK is plugged

    - Set terminal to 8bits/115200b/1 stop/No parity on OTG FS

    - Reset while pressing joystick up button

Please retry

when i change the baud rate to 115200, the module does not respond

i'm using windwows 10 and also ubuntu 19.04.

Hi,

i am in your situation. i write you a message to collaborate if you want

[KBADA.1]

i solved it

to activate the AT commands, you must: check the correct position of the jumpers:

JP3 -> ARD_V5_IN

JP4 and JP5 -> + 3V3 JP 6 -> positoin 1-2 (to the left)

JP7 -> STLK

 JP8 -> closed

 JP9 -> open

- Open gtkterm or other similar utility and set the baud rate to 9600, bring it to ACM0 and wait for the STM welcome message to appear. - Once the message is displayed, briefly press the "RESET" button and hold the joystick UP. - Once this is done, a message is displayed indicating that we can talk to an AT command

- you have to open a new terminal and run gtkterm but this time choosing the port "ACM1" and the baud rate on "115200"
