B-WL5M-SUBG1 Power consumption measurement
Hi All,I am working on B-WL5M-SUBG1 hardware.I compiled the example "C:\...........\STM32Cube\Repository\STM32Cube_FW_WL_V1.3.0\Projects\NUCLEO-WL55JC\Examples\PWR\PWR_STANDBY" to measure the current consummed in standby mode and I am measuring the ...
Can't transmit data with LoRa
Hi everyone,I have custom stm32wle board that is configured as dc-dc supply, and external 32MHz crystal with 6.8pF capacitors.I can read and write to/from radio registers but i can't transmit any data. Indeed even transmit interrupt (HAL_SUBGHZ_TxCpl...
Unexpected Power Draw on STM32WL55JC1 Custom Board with LoRaEndNode
Hello,On a custom board based on the STM32WL55JC1, I managed to flash a version of the LoRaEndNode application. However, when I run it, I observe an unusually high power consumption of around 70 mA.In contrast, when the board is in programming mode o...
Resolved! Wrong Image in NUCLEO-WB55RG Manual UM2435 - Rev 3
Hi, There's an image in the NUCLEO-WB55RG user manual (UM2435) with the phrase "Wrong Image". Not sure what this is suposed to mean, maybe an internal doc note? ST Doc team, can you please review? Best, Alessandro
Resolved! STM32WB55 ADC Internal Resistance Issue
Hello STM Community,I’m currently working on measuring a LiPo battery voltage using one of the ADC inputs (AIN6) on an STM32WB55RG. The battery voltage ranges from approximately 3.0 V to 3.95 V. Since the ADC reference (Vref) is 3.3 V, I used a volta...
Resolved! LoRaWAN Software Stack for STM32WLE5xx
How I get the software stack/firmware library stack with LoRaWAN for STM32WLE5xx MCU (other than Seed Studio Library) ?. In github, stm32wl repository only has a STM32WL55JC drivers alone. Is there any possibilities to get a firmware stack for STM32W...
Sequencer stop when LPTIM1 Started
I am using the LoRaWAN_End_node application. The application was working fine until I integrated the Low Power sample code. The Sequencer appears to stop working (I suspect the timers are not working). If I do not do add MX_LPTIM1_Init() in main e...
STM32WB55 - unexpected current pulses in STOP2 and standby modes
Hello,I'm developing a battery-powered application for the STM32WB55 (specifically the STM32WB55RGV6) and am seeing periodic pulses or spikes in the SoC's current consumption every 200ms in STOP2 and standby modes. These pulses occur with the Nucleo ...
