STM32 MCUs Wireless

(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.

FLASHEx_Erase returns HAL_ERROR only when TIM16 is activated in CubeMX.

Hello,I asked this question once, but I feel that I explained the problem inadequately.I am attempting to write to internal flash memory and am following the (UNLOCK, ERASE, WRITE, LOCK) approach. Everything writes fine in the simple code I have writ...

Hi, I'm trying to enable the Bootloader Mode on my STM32WB55. I succeeded in doing so and the DFU in FS mode is shown in the device manager.I downloaded the DfuSe Demo application and there is nothing in the available DFU Devices section. any help? thanks

Nucleo stm32WL55 LoRaWAN_Endnode SMPS, current in STOP2 is between 160uA and not 2uA

Hey there, i have a problem with the Nucleo STM32WL55 Board, i'm trying to reduce the current of the board in the LoRaWAN_EndNode application. When the uc is running i got something between 160uA, but in the datasheet it says that the typical current...
