Hello,
I observe that the modem is sometimes getting out of deep sleep for an unknown reason.
What are the wake up sources and how can we identify it ?
Regards,
Alex
Hi Alex:
Are you using PSM or eDRX? do you know your configuration for PSM and eDRX?
Modem will be wakeup when host try to send something.
or network side has some activity to reach modem, like LWM2M service or other traffic communicate to modem.
If possible, try to connect UART2 ( console) and record the console log from beginning for checking.
One thing to check is UART1, do you use UART1? if not, suggest to disable it because RTS1 is one of the wake up source, if it’s floating because no pull up in your design, then modem might be wake up unexpectedly.
AT+CFUN=5
AT+SQNHWCFG=“uart1”,“enable”,“rtscts”,“921600”,“8”,“none”,“1”,“dcp”
AT+SQNHWCFG=“wakeRTS1”,“disable”
AT^RESET
