Resolved! How to use BLE_p2pServer example with NUCLEO-WBA52CG board?

Hi,I would like to use the BLE_p2pServer example with the NUCLEO-WBA52CG board as shown in the MOOC example with the NUCLEO-WBA55CC board. Unfortunately, I can only find this example for the NUCLEO-WBA55CG via the “Example Selector”.Is there a way to...

Resolved! Quad SPI Single Mode Read Chip ID from Riverdi

Hello,I'm using a Nucleo-WB55RE board with Quad SPI in single mode. I'm trying to start very simply by just reading the chip id from a Riverdi BT81X display. I have captured two waveforms, one via a Nucleo-446 board using regular SPI and one from t...

I am using a NUCLEO-WL55JC1 and the LoRaWAN_End_Node example. I want to add USART1 to the example, so that I can forward the UART data over LoRa. The problem is that the interrupts for USART1 never trigger if the LoRaWAN process is also running.

If I comment out "MX_LoRaWAN_Process();" in main, then the USART1 interrupts trigger as they normally would. Could anyone offer some advice of how to add USART1 to the example?Kind regards
