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...
Resolved! STM32WL31 fails to exit DEEPSTOP from RTC wakeup
Good day,I have a simple custom board with a STM32WL31 that needs to cyclically enter DEEPSTOP mode and then wake by means of RTC internal wakeup. It seems the device enters DEEPSTOP, but does not wake from it. Basic setup:Clocked from HSI, RTC clock...
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 ...

Resolved! STM32WL30XX PCB Antenna Design
I need support for the design of STM32WL30XX PCB Antenna. Are there reference designs available for the PCB antenna?Specifications:Two layer board Output power 10dBm in the 868MHz band.
LoRaWAN_End_Node_LBM v1.5.0, US915, B-WL5M-SUBG1, TX Power Too Low - with possible solution
In testing the LoRaWAN_End_Node_LBM application supplied with STM32CubeWL-1.5.0 release I found that the output power is substantially lower than the same test setup with the LoRaWAN_End_Node application supplied with STM32CubeWL-1.4.0. This testing...
Resolved! STM32-compatible End Devices and Gateways with LR-FHSS Support?
Hi everyone,I’m currently working on a project involving LR-FHSS and I’d like to know whether there are STM32-compatible end devices and gateways that already integrate LR-FHSS-capable radio chips.From what I’ve found so far:End Devices (sensor/node)...
