Resolved! W-MBus Example Code for WL55JC1

Dear All,Our work is focused on the STM32 WL55JC1 board!What we would like to achieve is use its RF transceiver as W-MBus.It seems that WL55 is suitable for WM-Bus since its transceiver supports the appropriate frequencies and modulations for such pu...

Resolved! STM32WB1MMCH6TR Power Consumption Issue After OTA Update

Hi everyone, I'm facing a problem with my STM32WB1MMCH6TR. After performing an OTA update, the power consumption jumps from 120µA to 2.5mA, which is significantly higher than expected. Interestingly, the power consumption returns to normal after I po...

Having issues enabling the SubGhzSPI on STM32WLE5JC

I have five identical development boards that I am attempting to bring up. One of the boards works without issues. The other four all fail during MX_LoRaWAN_Init(), After digging a little deeper I found that the SubGhzSPI peripheral is never getting ...

Resolved! STM32WB10 wireless stack

Can someone confirm that the STM32WB10CC does not come pre-programmed with the BLE stacks? I'm assuming they are not pre-programmed, because I've used FUS in STM32CubeProgrammer to see if I can Start Wireless Stack. When I do, a message pops up stat...

Matching impedance between WB09 and MLPF-NRG-01D3

In the documentation for STM32WB09 it is written that the output impedance of the chip is 40 ohms. It is also written in the document AN5526 on page 5. And in the documentation for MLPF-NRG-01D3 chip it is written: Transmission line between STM32 and...

Lorawan Interrupt taking more power STM32WLE55X and LPTIM is not working with Lorawan

HiI am trying to interface the STM32WLE55x lora module to a pulse counter. when I tried with interrupt as a counter (as i have to count the pulses!!!) its taking 123mA current at the time of sending the data to server and on ideal condition it is ta...
