I am struggling using 4G and sending SMS same time with EC25-E module.
It looks like the Raspberry sees the board in several ttyUSB0-3 but in real case there is only one port which works.
Using sudo pppd call gprs
and trying to connect with minicom for sending sms with AT.
Is there some way to use this at the same time?
You can use ttyUSB2 for send AT commands at the same time.
