Hi:) I've problem with SIM900 module. Seems to me that it's not able to maintain a connection. What i know this firmware is supporting europe (i come from Poland). SIM has no PIN code and it's properly working on smartphone. Firmware version:
SIMCOM_Ltd
SIMCOM_SIM900B
Revision:1137B09SIM900B32_STResponse for "AT" Command:
OK
It's detecting an operator:
AT+COPS?
+COPS: 0,0,"Orange PL"But signal quality is 0:
AT+CSQ
+CSQ: 0,0
OK
Led status: https://www.youtube.com/watch?v=AY6JEwgJMM0&feature=share I'm powering it from laboratory power supply which is set to 5V DC and current limitation set to 2A. Any tips what can be wrong?
