CONNECTING NRF52 TO RASPBERRY PI

[varun k]

Hello guys,  

                 I am using nrf52832(PCA 10040) and transmitting  radio packets. I want to collect the packets using raspberry pi. Is it possible?. If yes, how are the ways we can do it.Thanks .

What "radio packets" ?

When you plug the PCA10040 into your Raspberry Pi's USB, does it show up as a serial port - ttyUSB... ?

If it does, that's probably the easiest way for it to talk to the Pi.

Otherwise, wire a UART connection to the Pi's UART ...

Thanks for the reply. I am using nrf52 modules as end nodes and they have proprietary rf(esb) -tx example loaded. we are thinking to use raspberry pi as gateway. So, my query was can we directly catch those raw radio packets with raspberry pi without using nrf-dongle. Or inserting a dongle is the only way to capture the packets?.

Remember that we can't read your mind - so you need to make things clear in your posts!

You would have to delve deep into the depths of the radio chip(s) on the Pi to find out if this is physically possible.

If you find that it is, then you would have to delve deeply into the Linux software to re-purpose it to do what you want.

Do you have the skills & experience to do that?

If not, then doing it on an nRF chip and just using a UART connection to the Pi is probably going to be the easiest approach...

I do not have those skills and experience, so i will go with using UART connection.

Hi 

I agree that sounds like the best solution. 

If you want something smaller connected to the Pi you can get an nRF52840 dongle rather than an nRF52DK, but this will require slightly different code to be developed. 

Best regards

And the Dongle is not designed for developing code - so do your development first on an nRF52840 DK.

Yes, the code development is already done on DK, I just need a small sized device like a dongle. Thanks a lot.
