STM32WL RF Layout – Routing Signals on 3rd Layer Near RF Section & Stack-up Changes

Hi everyone,I’m working on a 4-layer PCB design using the STM32WL (based on the Nucleo WL55JC reference design).For the RF section, I followed the same layout approach as the Nucleo board, including the layer stack-up and RF trace widths.The only dif...

Resolved! Does the STM32WBA65 support the channel sounding feature of BLE 6.0?

The product page and datasheet only mention BLE Core 6.0 but don't call out channel sounding support explicitly like other BLE features. Is it actually supported?

STM32WLE5: LSCO pin behavior during Run ↔ Stop2 mode transitions

Hello, I am working with STM32WLE5CC and using the LSCO output (configured via HAL_RCCEx_EnableLSCO(RCC_LSCOSOURCE_LSI), source = LSI) to observe the low‑speed clock externally. In my application: LSI is used as the RTC clock sourceRTC is used ...

Resolved! How to implement button interrupts in STM32WBA65I-DK1

I'm developing using the STM32WBA65I-DK1. I'd like to know how to implement interrupt handling for button presses. It appears that stm32wba65i_discovery.h does not contain any APIs related to button presses (which is perhaps to be expected since the ...

LoRaWAN_End_Node_LBM with Shutdown mode

Hello,My goal is to wakeup the end node to send a single frame then go to shutdown mode, but I'm having some hard time putting the device in shutdown modeI am calling HAL_PWREx_EnterSHUTDOWNMode(); in LoRaWAN_Process() function, after checking on a s...

STOP mode and BLE

Hey. I currenlty have a wba55 baord and use it as a ble p2p server. The main idea is to put put the board to stop0/1 mode when disconnected so that it consumes some μ amps and turn it back on when receiving a specific interrupt (eg button, timer etc)...

Resolved! STM32WLx5 min LoRa operating voltage

Hello,there are different statements on the minimum operating voltage for LoRa operation.STM32WL5-PWR paper says 1.95V,STM32WLE5 ref manual says 1.8V (section 5.3.3 Transmitter).What's correct?

Resolved! STM32WL55 output RFO_H output impedance

Hello,I am using a STM32WL55 UFQFPN48 in an application. I am only using the high power output (up to +22 dBm) and only plan on transmitting with this device.I want to transmit in the 420-440 MHz range, but there does not seem to be any load-pull ana...

ADC reference for STM32WL31 VBAT measurement

Good day,I want to measure the VBAT voltage of a STM32WL31 using its ADC. I setup the ADC channel as follows using the ST HAL driver:ADC_ChannelConfTypeDef ConfigChannel = {0}; ConfigChannel.Channel = ADC_CHANNEL_VBAT; ConfigChannel.Rank = ADC_RANK_1...

STM32Cube FW_WL V1.5.0

I upgrade my project recently to the above firmware (STM32Cube FW_WL V1.5.0) which ended up not working.Lots of errors, I think mostly because of the introduction of the relay node.After a couple of days trying to get this working I started a fresh ...
