STM32WBA family use of stack BLE without LSE (with LSI2)

Wladimiro_Gaiotti

Hi to all!

We are developing a low-cost application, with in mind STM32WBA52KE, which use a 32 pin package.

Due to short number of pin, we would use pin 12 and 13 as GPIO, so we should not use the LSE.

Is it possible to manage the BLE stack without LSE, using LSI2? If yes, which kind of limitation we will have?

I can't find the right answer on documentation, can you help me?

Thank you very much in advance.

Hello @Wladimiro_Gaiotti and welcome to the ST Community .

It should be working fine since there is no API that depends only on the LSE clock.
