Resolved! Device not found BLE after copying project
CubeIDE, P-Nucleo STM32WB55 I have a BLE project that works, it sends data from 2 temperature sensors & 2 accelerometers (x, y & z for each)Within Cube I copied the project then pasted with a new name.Added some code to take 1000 samples of the accel...
WBA54 BLE OOB pairing on IOS
I've tested the OOB function using 2 BLE MCU WBA54,case 1, one provide the OOB data then send to the other case 2, both proved the OOB data then send to each other 2 cases are OK, pairing success and bonded.OOB data provide use:ret = aci_gap_set_oob...
Resolved! SPI & I2C not working when Nucleo-WB55 powered by external source
I'm working with an STM32WB55 Nucleo board and encountering a strange issue. My project uses an SPI display and an I2C accelerometer, along with BLE.When the board is powered via the ST-Link/USB, everything works perfectly: the BLE functions, the onb...
Resolved! NUCLEO-WBA65RI BLE and Low power
Hello everyone,I am performing some tests over the NUCLEO-WBA65RI board, related to low power mode and BLE functionality.I managed to test the BLE_p2pserver example correctly and checked the current consume is about 500 μA on this case until it goes ...
High Peak Current (17-18mA) in Active Mode on STM32WB55RG After RTC Wake-Up from Shutdown
Hello STM32 Community,I'm working on a project using the STM32WB55RG microcontroller (specifically the P-NUCLEO-WB55 evaluation board) to implement a sleepy end device in a Zigbee network. The goal is to transmit data over Zigbee periodically and the...
