Hi there
i've problem with SIM900 mini module.
My problem is that SIM900 is not getting steady signal.
Response for "AT+CSQ" command is generally +CSQ: 0,0, sometimes +CSQ: 10,0.
Signal LED Status: https://www.youtube.com/watch?v=AY6JEwgJMM0&feature=share
For me seems that SIM900 is getting restarted after establishing a connection.
I saw SIM900 reset topic (https://www.edaboard.com/showthread.php?303408-Sim900-Reset-Problem) but i'm powering it from it from laboratory power supply which is set to 5V DC and current limitation set to 2A.
Response for "AT" command is OK.
SIM900 firmware:
SIMCOM_Ltd
SIMCOM_SIM900B
Revision:1137B09SIM900B32_ST
I've checked it for two different antennas, the same result.
I will be grateful for tips what can be wrong.
