We are designing a project which uses a switch, if it turns I want my module to send SMS to specified number,But we are not able to setup connection in module it is blinking at rate of 1 per sec, I’m using Vodafone 4g please help
does “vodafone” appear in the available services list?
1 pulse per sec indicates not connected, maybe you are in a poor signal area??
Yes it displayed Vodafone
what code is returned when performing AT+CREG?
