Hello All ...
I am using SIM900A module ,, Fabricated a good PCB ,, The module is not accepting any command but echoing every command ,, I am unable to set echo OFF , I am using SIM900A V2.03
I've spent too much time ,, but got response of only following command
AT+IFC=1, 1 (Software Flow Control)
after executing above command , when I switch OFF the module then get the following message ...
NORMAL POWER DOWN
Status LED is Constant , While NETLIGHT LED looks like following ..
64ms On/ 800ms Off => SIM900 does not find the network
*** VDD_SIM are 0.02V all the time , Which is suspicious***
Please help me out ,,,
Thanx in advance
Maan
