Compiling Espruino for NRF52840DK without Blutetooth

Thanks for the detailed explanation!
The hex file you provided indeed does not run on the NRF52840DK. But i tried your fixes in jshardware.c and they worked. Even tho i got a linker error here (undefined reference to app_ram_base):
https://github.com/espruino/Espruino/blob/edc64ce1ab231c608110797546ffa9d445745425/src/jswrap_process.c#L159

I just added defines to ignore these lines if bluetooth is disabled.

   return obj;

It compiles and runs on the NRF52840DK and is the desired result i was looking for.
I think removing Softdevice entirely would save a lot more memory but it is not needed for my application.
Thanks alot!
