I thought @GS2 was making a Bluetooth mouse?

A Bluetooth mouse should be able to connect to any standard Bluetooth "host" - that's the whole point of the Bluetooth standards & Profiles.

But, yes a programmable dongle like the ST STM32WB55CG dongle could give extra facilities for use during development/debug.

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.

Hello @GS2 

The USB Dongle based on the STM32WB55CG is an evaluation board with a USB User that can be used to communicate with the Laptop or for connecting and prgramming the MCU since it doesn't include an ST-LINK integrated. To programme this Board, you can refer to one of the following examples as a start to your project. For the STM32WB5MMG module, you can connect it to the USB Dongle board based on the STM32WB55CG.

Best Regards.

Thank you STTwo-32 for your response, but lets put my question this way: after I finish the wireless mouse design and made my board with the STM32WB5MMG module on it - is there any standard Blue Tooth USB dongle that can be connected to computer/laptop to work with it or I will need to make something similar to STM32WB55CG (USB dongle) to work with my wireless mouse ?

Thank you STTwo-32, but do you know the STM32 controller that can communicate with Bluetooth 5.0 standard dongle?
