Resolved! HardFault occurs while trying to run STM32WB55 BLE examples on custom board.
Hi all,I have my own customized board based on STM32WB55RGV6. The board has HSE of 32 MHZ but don't have LSE. I am using LSI or (HSE/32) as RTC clock and HSE/1024 as RF wakeup clock. I am facing two different problems.Case 1: First I tried with examp...
Resolved! How to make STM32WB55 work as LE Audio device?
I've seen that it's support Bluetooth 5.2 which added LE Audio feature.Is it possible to make SSTM32WB55-based sound device (i.e. BLE to 3.5 mm jack converter)?And how if so?
Resolved! Timer cycle duration is always the same
Hello,My firmware sends data to TTN when I double push on the button of my board. When the first push is detected, the board wakes up from low power mode and a timer is launched to detect if there is a second push. At the end of the countdown, if the...
Do you have ETA Certificate for the STM32WB55 Series Controller?
I am using the STM32WB55 Series for my application. I am using BLE and Zigbee on this MCU. I am registering my devices for FDA/CDSCO certification. The department is asking for ETA certificate. DO we have ETA Certificate for Controller?
CPU2 and SDK support
I already got it: CPU2 is not accessible by customer (at least, using official SDK).Anyway, we have an WB-based project that will hugely benefit from offloading some resource-consuming tasks to CPU2. They are not related to radio, we're not using any...
Resolved! Not generating PWM signal after wake up from STOP2
I'm working with STM32WL and trying to be able to generate PWM signal after wake up from STOP2 to control RGB LED. Before going to STOP2 I deinitialize PWM channel pin and disable timer clock. MCU wakes up on button press. After wake up timer clock i...
The software freezes when using adc in the sequencer of a Zigbee application on stm32wb5!!!
Hi,I am using Zegbee messaging cluster on STM32WB55 to send messages between some Zigbee end devices and a coordinator.Each end device measures the temperature via I2C sensor and sends a message with the temperature value to the coordinator and then ...
how to learn STM32 Debugger?
I had one STM32 debugger (ST-LINK-v2). how to learn the STM32 debugger and how to connect the stm32 chip to the debugger. give any solution or tutorial.I will be waiting for your replays. Thank you.
No RX timeout IRQ after RX in single mode with timeout
If I call SUBGRF_SetRx() with a timeout of, let's say 100 ticks in LoRa mode, I don't get an RX timeout IRQ at the end of the timeout.I have checked the radio status with SUBGRF_GetStatus(). The radio goes to RX then back to standby.I have cross-chec...
[STM32WLE5JC][LoRaWan - End_Node] How to change device_eui, epp_eui, app_key from program ?
Hi,I have build a custom application from end_node project example on LoRa-E5 board.All works fine with comissioning from CubeMX.But now I want to use values loaded from flash.So I added 3 variables :uint8_t device_eui[8];uint8_t app_eui[8];uint8_t a...
