(STM32WL55) What purpose does the "TCXO_WORKAROUND_TIME_MARGIN" delay serve? Can it be removed safely?

Sample code includes a 50ms delay "TCXO_WORKAROUND_TIME_MARGIN" in addition to the Radio.GetWakeupTime() when moving from RX to TX. Is this a necessary delay, and if so, why? Higher data-rate LoRa configurations are significantly bottlenecked by this...

STM32WLE Reference and Bandpass Filter Considerations

Hi!We are developing an ultralight, ultra low power IoT device and the STM32WL seems like a great fit.We have chosen the STM32WLE5CCU variant (M4 MCU, 256kB, UFQFPN-48) because we don’t need the extra processor core. When designing the board, I ran i...

Data transfer between two P-NUCLEO-WB55

Hello,I would like to transfer data between two P-NUCLEO-WB55 boards. I took a look at the p2p-Server/Client example and I think this is just what I need. I used the project templates from CubeIDE and created two own versions. For this I followed thi...

Is it possible to create a BLE Router application with STM32WB10CC?

I've been using a WB55 for a BLE Router but supply shortages have meant we need to switch to using a WB10CC. I noticed that there is no example from ST for this chipset. My initial attempts to adapt the WB55 example haven't been productive.
