Resolved! Difference OTA procedure ST BLE ToolBox vs ST BLE Sensor IOS apps
Hi ,I'm trying to Perform OTA update using ST BLE ToolBox ,I have programmed my STM32WB5MMG with the OTA binary.The problem comes when starting the update process. With ST BLE Sensor there is no problem: the device is updated to the new version of th...
Looking to operate WL55jc1 and L072Z LRWAN1 in Class C.
@ST Community @STTwo-32 @Tinnagit @Tesla DeLorean 1) I have done few changes from "#define LORAWAN_DEFAULT_CLASS CLASS_A" to "#define LORAWAN_DEFAULT_CLASS CLASS_C" in the "lora_app.h" file and I also changed "#define DISABLE_LORAWAN_RX_WINDOW 0" to ...
Resolved! Issues migrating from stm32wb5mmg to stm32wb1mmc
Hello.I have encountered an issue during the migration from STM32WB5MMG to STM32WB1MMC.When I generate the default code using CubeMX with STM32WB1MMC, no errors occur. However, when I try to transfer the code I was using with STM32WB5MMG to STM32WB1M...
What is the impedance of STM32WLE RPI differential pair?
Do I need to set the net impedances of differential pair from RFI_P and RFI_N to 50ohm?
ADC multichannel using DMA can't trigger Analog watchdog interrupt correctly
Hi.I'm using stm32wb55 MCU.ADC is running in continuous mode with 6 channels using DMA for the results. I want to use analog watchdog interrupt on just 1 channel that is on rank 2.I have 2 problems, first the interrupts occured only for the channel i...
