[SOLVED] No bluetooth connection after flashing NRF

Hello,
I updated the NRF firmware on my CF 2.0 with the make target
cload BLE=0. It worked fine, but since then, my android phone isn't able to connect to the CF via bluetooth (using the CF app, of course). Seems obvious due to the BLE flag set to 0, but even after flashing with
BLE=1 the bluetooth connection attempt always times out.
I followed this guide:
viewtopic.php?f=5&t=1678&p=8688&hilit=flash+nrf#p8806
Before flashing the NRF the bluetooth connection was alright, so what am I missing?

Hi alex,
I'm a little confused...
Did you run:
and then you ran:
'make cload' only
flashes the NRF (no compilation) so I
believe that passing BLE=1 to this make target is meaningless.
If you try to clean the project, then make it with no arguments (
which is the same as saying BLE=1), then cload, do you still have an issue connecting? I just tried that and it worked OK for me.

Ok, obviously I didn't know what exactly I was doing, thanks for bringing me on track.
This did the job!
Can you recommend some basic reading about make files and related stuff in general?

Awesome! Glad you got it fixed!!
I'm not sure exactly what you're looking for. I read the actual Makefiles themselves and the READMEs in the repository. But I also have 15+ years of software build engineering experience.
If you're looking for a tutorial on 'make' and Makefiles, have a look at
these M.I.T. OpenCourseware lecture notes but keep in mind it is
very basic.
