Hello,

Maybe a rookie question but i am having some troubles with setting up the P2P communication following the documentation here: https://www.bitcraze.io/docs/crazyflie- ... r/p2p_api/

I am trying to follow the simple instructions in the documentation page in order to compile and then upload a new firmware on the Crazyflie.

My actions:
- I cloned the repo crazyflie2-nrf-firmware
- I am trying to compile the firmware following the instruction in the documentation page (clearly from within the correct folder crazyflie2-nrf-firmware), that is:

Code: Select all

make clean
make BLE=0
make cload BLE=0

When I execute

Code: Select all

make clean

I obtain this message

Code: Select all

Any suggestion?
I am not an expert here so any kind of help may be beneficial

Kind regards,

Hi!

So it seems that you are missing the NRF files from nordic. Are you sure you followed all the readme of the repo, including the './tools/build/download_deps' as indicated on the top?

The interesting thing is, is that with BLE=0 you wouldn't need it anyway.. but that is maybe another issue. Actually, the p2p functionality should now work with the latest master with BLE support compiled (so just with 'make') which was fixed in this issue: https://github.com/bitcraze/crazyflie2- ... /issues/34

Hei,

Thanks for your reply and support!

Something must have gone wrong with the installation of the packages.
I fixed that and I will take it from here.

I am sure I will come up with more questions later
