I have STM32 board connected with main uart of ec25.
Then to send at commands via uart, I started
quectel-uart-ddp -uart /dev/ttyHS0 -smd /dev/smd8
code from command line. I can take response in idle state but when I started calling and checking CALL status with AT+CPAS, sometimes data comes corrupted with junk characters. Why this can be happend? Normally, I can communicate but when call occurs, UART is going crazy? How this can be solve?
Dear Ye110w,
Thanks for your inquiry in Quectel forum.
About your issue, i have some information need to confirm with you:
- you use Openlinux solution, not standard AT solution right?
- If yes, it is better to create the topic in the subject Open solution.
3.If not, it is better to provide your test AT log, then we can help to check the reason. - You also can use windows test log to check it.Thanks!
