STM32WB1MMC module on 4-layer PCB

[_Ben]

My current project is a small (15 x 30 mm) PCB, with 4 layers. I use the STM32WB1MMC module for BT connectivity.  Are there things to consider when designing this 4-layer PCB in order to maximize BT range?

Thanks!

Hello @_Ben 

I will recommend you follow the recommendations of the AN5265, the DS14096 and the design of the 

B-WB1M-WPAN1 as a reference for you. 

Best Regards.
