  • I fully agree. This module is unreliable and seems to live its own life. I’m trying to use this module to control my Arduino over TCP/GPRS. It works, at least for a few minutes. Then the module resets for no reason. If it loses coverage (even for a couple of seconds) the connection is dropped and wont reestablish without a hard reset.
    This works, the module establishes a connection to my server and I’m able to send data back and forth via the SSTRSEND command. Now, lets say I use my GSM jammer to have it drop the connection for a couple of seconds, then it looks like this:
    +SOCKSTATUS: 1,1,0102,160,148,0 //Says socket still connected… not true
    AT+SDATASTART=0,1 //Attempt to disconnect fails
    +CME ERROR: 65536014
    AT+SDATASTART=1,1 //Attempt to restart the connection returns OK… But nothing happens.
    Bottom line: Do not buy this product.

No public wish lists :(
