In my computer

AT+QIACT=1
->OK
AT+QIOPEN=1,0,"TCP","110.165.17.3",9091,0,2
->CONNECT

is success.

But fail NO.2 in my raspberry pi4 bash.

atcom AT+QIACT=1
->OK
atcom AT+QIOPEN=1,0,"TCP","110.165.17.3",9091,0,2
->ERROR

what am i wrong?

atcom AT+QIGETERROR
->+QIGETERROR: 552,invalid parameters
OK

i guess i use same parameters..

I installed atcom as described, however I cannot connect to the Telit modem. Any AT commands result in the same error.

pi@raspberrypilte:~ $ atcom --port /dev/ttyUSB2 -b 115200 AT
[ERR]   Couldn't open serial communication
pi@raspberrypilte:~ $ 

If I run the connection via minicom minicom -D /dev/ttyUSB2 -b 115200 , everything works.

RasperryPI Bullseye, Python 3.9.2 installed.

EDIT:
It found a connection at /dev/ttyUSB3. I accidentially tried USB2 since this is the right port address when I use minicom.
However, the the automatic port scan seems not to work as I always need to add the -p option.

Baudrate setting from the cli does not work.

root@9854bd3:/# atcom -v AT -p /dev/serial0 -b 230400

I can set the value from the config though.

When I try to send text messages via "atcom AT+CMGS="my_phone_number", "CR", "Text message text", I always get a timeout error. I'm able to send other AT commands without issue. I think the problem has to do with how atcom terminates the message stream, but I'm not certain what I need to change to fix this. Any help would be greatly appreciated!
