Unfortunately i cannot update the firmware of my XBee 3G Module (XBC-M5-UT-001) – my research so far has been fruitless – Digi Forums recommend to get the original Dev Kit as they blame 3rd party USB implementations.
I am using the latest XCTU version – If i try to update after a while XCTU will ask me to reset the module but that wont help.
Has anyone else experienced these problems with other or similar XBee modules?
PS.: Side Note – You have to disable all outgoing Traffic via the UART2 on the F9P otherwise a stock XBee 3G will keep crashing and you wont be able to connect to it at all.
Update: It seems as if the CTS and DTR Pins of the Srtk2Bs XBee USB TTL Chip are not connected to the actual XBee Pins.
I used a FTDI USB TTL Converter and connected these two extra PINs, then the firmware update worked like a charm.
We confirm they are not connected, firmware update should be done on an XBee evaluation board.
