    I would like to use the AT Command Tester with a SimCom SIM808 module.

    After software release 1418B01SIM808M32, (about 2015-04-10), this module uses GNSS commands in place of GPS commands (see

    Are there any plans to update the AT Command Tester to accommodate these later versions of the module?

    Thanks A.K.

    I am facing a unusual problem with SIM808 GPRS operation.
    Everything worked fine before. Problem now is that when I send “AT+SAPBR=1,1” manually, SIM808 goes in infinite loop of “There is GPRS data transfer in progress”(according to datasheet, NET LED blinks every 300ms). I have not connected any other device with SIM808 and commands are sent manually.
    I would love to here a suggestion if any. Thankyou.
