Hello,
I'm making some sensors based on nRF52832 and I'm using them as native transceivers. Maybe I'll look at BLE Mesh in the future but at the moment I just send and receive packets through the radio peripheral.
Now, I want to add the nRF52 family on a Raspberry Pi. There's two ways to do that.
The first is to connect an nRF52832 using a UART or I2C or SPI.
The second is to buy a nRF52840 dongle and plug it on the USB port.
The firmware development might help me make the right decision here but I've got a few questions about it.
Is there any prebuilt firmware that will help me to use nRF52840 dongle as native tranceiver? I don't want to write my own firmware again as I did on nRF52832. If I have to do that I'll definitely prefer to use one of my modules and plug them onto the Pi and go with the first case.
Is there any advantage for me in that case to look at the nRF52840 dongle?
I note again that I'm not interested in just a BLE application as I'm trying to implement my own protocol.
