Hi there
I am working with Arduino and Sim800l module
I want to check whether Sim800l is connected to the network right now or no? If the connection is established and OK at the moment, I want to send a message and if the connection is off, I want to print something.
How can I do this?
(For example, is there any method to return a Boolean for connection checking? (If connected, True or ...))
I will be more appreciated if your help contains a code example.
try AT+COPS? command, e.g. using a QUECTEL E£C21 modem connected
