How can I use QextSerialPort on two different serial ports in the same time?

Hi,

Maybe it's not the matter, but it seems to me that you start 2 timers with a 0 interval time.
Is it correct? Your CPU should run at full charge, maybe that cause some trouble in the reception? Have you try with a reasonable time interval (250ms for instance)?

Loopback the wire can tell you if you're wrong on the protocol/in the serial configuration or if it's a software problem.

Thank you for your feedback. I have tried to change the GSM terminal with something other, and then I got some input. The baudrate is correct. So something in my code is a little tricky.
I will check the timers
