Determine Firmware version on module?

2 thoughts on “Determine Firmware version on module?

  1. I am working with the GC864 Guad V2 and I can’t get the FTPGETPKT command to work.


    I am wondering if it is because there is an older firmware version  on the module.


    Is there an AT command to determine what firmware version is running on a module?

    1. Is AT+CGMR Ben, please keep AT Commands Reference Guide at hand. Set AT+CMee=2 and investigate error message.
