Resolved! RTC is not incremented with a voltage Vbat below 0.6V
Hello,we use an STM32WB55 with an RTC backup via a super capa.when the Vbat voltage drops below 0.6V, the RTC registers are no longer incremented.if the board reboots at this point, we have a datetime offset.is it possible to detect this problem when...
Resolved! Using OLED and gyroscope of STM32WB5MM-DK
I am using STMcube ide for developing applications with STM32WB5MM-DK. I will be trying to use the OLED display and gyroscope of the discovery board. I couldn't find suitable tutorial or documents for accessing. Is there any documents available for t...
Manually sending an I2C stop command.
In the manual it says that a stop command will be sent with the next byte if the CR2 stop flag is high. Is there a way to send a stop command immediately rather than with the next byte? I'm asking because I have a section of code where I send a sta...
BLE GATT configuration: "Number of Services must be between 1 and 5" -- why?
When configuring BLE using STM32CubeIDE Device Configuration Tool with a custom template I can only set up to 5 services and 5 characteristics per service. What is the reason for that? Is there a possibility to set more services and characteristics p...
Resolved! STM32L0 LoRaWAN -> Whenever I set date and time to internal RTC, my system will crash.
Hello,I'm currently working with an STM32 microcontroller, and I'm facing a challenge related to the internal Real-Time Clock (RTC). Specifically, whenever I attempt to set the date and time using the internal RTC, my system crashes. I've reviewed th...
Resolved! Multitasking radio and sensor reading task.
Hello, I am currently building an application for the STM32WL. Two processes need to run simultaneously, the first is offline, and just reads data from a sensor and stores it in SD memory. The second is sending a LoRaWAN up-link message every 10 minu...
Fail to find my nucleo-WL55JC2 in the BLE Sensor App
Hello everyone, So I'm following the tutorial here https://www.st.com/en/embedded-software/x-cube-ble2.html to try a BLE connection from the nucleo-WL55JC2 connected to the BLE expansion board X-NUCLEO-BNRG2A1. I followed the tutorial and run the pro...
Inquiry on Minimum Delay Between Two Messages Using STM32WB's BLE LL Driver Stack
