BLE transparent mode firmware for STM32WB55VGQ package.

Hello,

Using custom firmware on an Inhouse designed board, the BLE output seems unmodulated as shown in the picture attached. But using the Transparent mode firmware on a Nucleo-Board (controlled via the Cube monitorRF) the modulation seems good (also attached)

So,

1. Is there any option to tune the modulation further other than default ?

2. Can someone provide the Transparent mode firmware for the STM32WB55VGQ package ? This can help in FCC testing.

This picture shows the sidebands when tx is ON on the 1st channel.

This picture shows there are no sidebands on the Nucleo Board which are coming in the above pic.

We tried by just changing the UART pins to the required one within the code and it worked using the Transparent Mode code used for the Nucleo Board.

So we can close this out.
