Flash error because of WiFi password characters

[fiechr]

I'm trying to flash the Backpack of the Happymodel ES24TX, using Configurator 1.3.4 and Backpack version 0.2 (TX version 2.1.0) under Linux.

While the TX worked fine with the same wifi password, with the Backpack I get this error:

I won't post my wifi password ;-), but it starts with 'wf###', which seems to be the problem.

<command-line>: error: pasting "wf" and "#" does not give a valid preprocessing token
lib/WIFI/devWIFI.cpp:53:5: note: in expansion of macro 'HOME_WIFI_PASSWORD'
