STM32WB55 > GFSK module access

[JL_Loyd]

Dear Community,

We do an update on a old product and the goal is to replace the nRF52840 by the STM32WB55.
The STM32WB datasheet is clear about BLE capacity but i would to know if we can use it without the Bluetotth stack, with my own protocol as we do with nRF52840.

In few words, is the STM32WB have the GFSK module open for do another things than bluetooth ?

Hello,

You can have a look to the Bluetooth® Low Energy low level driver (LLD) available on STM32WB, which provides access to the STM32WB Series radio device to send and receive packets in BLE radio format. BLE LLD is a radio communication layer. It relies on BLE radio hardware, it is a proprietary radio abstraction layer, and not a
BLE stack. BLE LLD provides a light and simple layer for developing proprietary protocols and applications.

For more information, you can refer to UM2804 which describes BLE LLD for the STM32WB Series products.

Best Regards
