I am trying to download the latest 6.61 firmware (C61b_q2687h.dwl) provided with the released Open AT v4.11 into a Q2686 that is currently running firmware:
660_09gg.Q2686H 1952244 030806 18:53
However, when I initiate a AT+WDWL and try and initiate a 1K XMODEM send from Hyperterm (version 5.1 on Windows XP), I get the following error message
*** ERROR IN DECOMPRESSION ***
followed by a bunch of garbage characters and the file download terminates.
This happens with both of the Q2686 modules that I received with the dev kit. I have never loaded any applications into the modules and I have tried stopping any potential applications using AT+WOPEN=0
Does anyone have any thoughts on how I can upgrade my firmware, so I can start using the latest release?
Any help would be much appreciated.
