Dear NXP,

 

I am working on SIMCOM GSM module. I am trying to execute AT command in this module. But, I am unable to access this module. 

 

I got the following reply when I try to read.

 

toradex_apalis6q:/ # cat /dev/ttyUSB3 &
[1] 1079
/system/bin/sh: cat: /dev/ttyUSB3: Try again

 

 

And also I check with all scenario (checking the user permission). But not workout.

 

 

Thanks & Regards,

VinothS
