STM32WB55 radio comms without bluetooth?

Hi,

I have to use the transceiver for pure RF communications and implement my own protocole.
After checking several boards, I've be recommended the P-NUCLEO-WB55 but from all the doc and example I find, the transceiver is used for BlueTooth communications, which I don't need at all.
Is it possible to use its transceiver RF without BLE, Zigbee, etc... as a simple 2.4Ghz range transmitter and receiver?

If not, which MCU should I get, that includes a dev board offering AD, DA and pure RF ?
Thanks for any light.

Hello,

you can create your own protocol built on 802.15.4.

Please have a look here for more information.

Does the RF need to be 2.4GHz ?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Andrew,

Yes it has to be in the 2.4GHz range, not sub GHz.

Hello @SteveJ 

As suggested by @FilipKremen, the 802.15.4 is a widely used communication protocol that enables the creation of Wireless Personal Area Networks (WPAN). So, it will be a good idea to use it.

Best Regards.
