I’m using sim868 alongside with airtel india sim card.
When I try a http post method occasionally I receive httpaction: 1,603,0 which according to the documentation says it is a dns error.
Set of commands sent
For gprs connection
At+sapbr=3,1,“apn”,“airtelgprscom” //assume a dot after gprs as not able to create topic with one
At+sapbr=1,1// for bearer connection
At+sapbr=2,1// for confirmation by checking the ip
I’m not finding the problem as I’m sending the commands according to the sim application note.
Any suggestions welcome.
Thanks in advance
