Hey there,
How we can use FCM360W AT commands in Linux environment. In windows i have use QCom tool to send AT commands and its working perfectly but its have many differences in Linux environment (Ubuntu) . also I’m using USB to UART to cable connect with my pc.

Thank you.

Hi Pojitha
Sorry but there is no way to run AT commands in linux environment for FCM360W

oh thank you the reason is in my project i have to connect the module using UART and i have to write a program in C to initiate AT commands in Linux environment. isn’t it not going to work?

There is no OS dependency. Just install a terminal app and make sure you have a driver loaded for your USB-UART adapter.

hey there, yes i have checked . its show like this .

$ sudo dmesg | grep tty
[    0.073256] printk: console [tty0] enabled
[    0.266680] 00:03: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[   11.183625] usb 2-1.3: cp210x converter now attached to ttyUSB0

but the problem is im not able to see the response from the module

Use a terminal app like this:
picocom /dev/ttyUSB0
You can bridge Tx and Rx on the adapter to test its operation before connecting to the module.

Thank you. i have tried it before but unable to type .

Well, then you probably need a different driver or another adapter. I see no issue related to Quectel module.

mmm , do you know any driver i can use?

It should work with standard Linux driver, until it is some newer revision of the adapter.
All my current adapters are based on other chips, so I cannot check the driver.
