Hey STI am building an application that has two power sources, one USB-C (27W) with the STUSB4500 controller, and an optional DC input.Because the GPIO or attach pins can be open drain, theoretically they could be used to contrl a second FET on the p...
Hello,What is the pin capacitance for SDA and SCL ? There is no information in the datasheet about this.Best Regard's,
Now the issue concluded to the source of issue. The value of Dtata is 0x38 but its not getting transfered to TFR. Though for other resistors its working fine. The value of TFR always stays 0x00000000. Since the data is not loaded to Tx FIFO, the com...

What is ST system bootloader address. I want to jump the application code to system uart bootloader as the boot pin is not available as of now.Thanks@Winfred LU @Eleon BORLINI
Running into lots of problems getting the BLUENRG-M2 to work standalone. When I hook up the expansion board (BNRG2A1), everything works, but not with this chip on my PCB. Verified power and signal wires. Every connection seems fine and I was able to ...
I'm using the SPBTLE-1S BlueNRG-1 module on a custom PCB with a STM32L4R9ZI MCU. The SPBTLE-1S module and the main MCU are connected trough SPI. The SPBTLE-1S module can be flashed with various firmwares provided by ST. Which one should i choose? I w...
Hello, Does anyone know if there is any SPI Flash memory reference source codes available for BlueNRG-2?Our device has additional SPI type NOR flash for file system extension but I couldn’t figure out how to configure it for BlueNRG-2.BlueNRG DK just...
Hi,i have x-nucleo-idb05a2 with STM32F401RE-Nucleo Rev C.I have put all Binary Application of X-CUBE_BLE1 but never see Bluetooth from scan or from ST BLE Profile.Why?
