I’m trying to upgrade the firmware of a Q24PL001 using Hyperterminal. All AT commands appear to work correctly except AT+WDWL:
at+cgmr 657_09gg.Q24PL001 1954500 102706 18:44 OK at+wopen=2 +WOPEN: 2,"AT v03.12" OK at+wdwl? +WDWL: V02.1B OK at+wdwl +WDWL: 0
But no symbols to trigger the XModem download start and the device will not respond to any more AT commands.
What am I doing wrong?
I’ve also tried DWLWin (126.96.36.199.3) which got to the end of ‘Installing Downloader into Wireless CPU’s memory…’ and then timed out (via grounding the BOOT pin via a 1k resistor).
