hello, We are using ST3232 as new project design and I measured waveform as below, does this waveform is normal or not？we use 3.3V power supply with 100nF ceramic capacitors. do you have a solutionthank you in advance
I have just started getting this and wanted to understand why and how to resolve. I have done a Mass Erase using the Flasher utility but that doesnt make any difference
Using the SDK's BLE_Privacy project as a base, I changed the Master & Slave programs to function with the static random address stored in NVM by commenting out the aci_hal_write_config_data function that was setting a public address and changing the ...
Good day.I'm pretty new to BLE and I've a pretty hard time getting the hang of it.I'm using the Sensor Demo example, delivered with the X-Nucleo-BNRG2A1.I've now a custom board with the BlueNRG-M2 as a coprocessor with a STM32F030C8T6 (SPI).The elect...
I'm having trouble with i2c communication. In my i2c bus, i have 4 boards (STM32L4 Sensortiles) and sometimes one of them blocks the bus and the others stop communicating consequently. When I reset that one that blocks the bus, all boards starting wo...
Hi, I'm trying to use STLINK-V3 MB1440B for BlueNRG2 debug. I'm connecting the SWD connector on STLINK to JTAG connector on BlueNRG development board. The BlueNRG-1_2 flasher shows "Waiting device to read ->" and stucks there when I tried to read the...
BLUENRG-M2SA is my processor. I am starting a gpio toggle to test it out. It compiles normally in Keil and Atollic. It only appears to use Keil program even when attolic is the programmer. The device will enter debug mode in Attollic how ever it ...
