Hello there,
Can anyone help me?
I have a SIM900 and I am trying to establish a connection to a POP E-Mail Server.
When I send AT+CIPSTART="TCP","pop.server.com","110"
Most of the time the above works and it connects ok, however sometimes it does not
AT+CIPSTATUS shows that TCP is connecting but it never does
What I want to do is wait a reasonable time say 10 seconds and if it hasnt connected try again
what commands do I need to send to have another go at connecting and in what order
AT+CIPCLOSE maybe
AT+CIPSHUT maybe
Do i need to resend AT+CIICR and AT+CIFSR before retrying with AT+CIPSTART
Any advice welcome
