Hi guys, I've ask Quectel support about reset signal (active low) on EC21 and this was the answer: ---- R&D said that if the reset low time is more than 480ms, the module will reset again. We suggest use PERST# only when failed to turn off the module by AT+QPOWD command and PWRKEY pin for protecting the internal flash. The fewer reset times of the module, the better.
So we suggest the reset low time to be no more than 460ms and 20ms margin reserved. --- _______________________________________________ ofono mailing list -- [email protected] To unsubscribe send an email to [email protected]
