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...
STM32WL55JC LoRaWAN Working Only on Dual-Core for FUOTA
I'm working on a project with the STM32WL55JC microcontroller. Before testing the LoRaWAN_FUOTA_DualCore application, my LoRaWAN setup was functioning correctly with all example applications.However, after flashing the LoRaWAN_FUOTA_DualCore applicat...
STM32WB35 drain more current in OFF mode than in STOP2
I 've made a realy simple app for testI'm using only 1 i2c and 1 spi and 1 gpio as input and 2 as outputI've set all unused gpio to analog to lower currentafter init it starts advertising and goes in STOP2 mode for 10 secI can see after the boot arou...
How to send complex payload via "aci_gatt_write_without_resp"
I've looked through many examples (in particular p2p client ) but I can't find any that sends payload that's made of array ```uint8_t pPayload[] = {0xFF, 0x01, 0x00, 0x05, 0xAA};uint8_t payloadLength = sizeof(pPayload);ret = aci_gatt_write_without_re...
WB5M & OTA
Hello,I have developed a custom board around the WB5M and I am working on adding OTA support to it using the sample code from CubeWB -> Projects -> NUCLEO-WV15CC -> Applications -> BLE -> BLE_Ota.I have modified this code to use CMake (following the ...
STM32WL55CCU6, power drop requires reprogramming
Good day, We have a battery-operated device using the STM32WL55.The battery voltage is regulated to 3.6V as supply to the STM32.We have found when the battery runs flat, the STM32WL5 would often need to be reprogrammed. This doesn't happen when we pl...
Resolved! Target Unknown Error 32
Yesterday evening I worked on an application for a Nucleo-WL55JC and STM32CubeIDE could connect to the ST-LINK just fine. I closed my PC and this morning started it again. I am trying to upload code to the CM0Plus core and now I am getting the follo...
Resolved! STM32WB5MMG LSE clock 32.774 kHz?
Hello all,I want to use the STM32WB5MMG module for a project which requires an RTC.The datasheet states the module integrates a 32.774 kHz LSE crystal. That seems a bit strange to me because the standard clock for LSE is normally 32.768 kHz. Checking...
