Yes, I read the Datasheet and studied the Evaluation Board Documentation. BUT those pins vanish in a "USB module".
I flashed the sample pre-compiled firmware on the STEVAL-BCN002V1 BlueNRG2 tile. The flash was completed successfully. However, I see only green led on the board and none of the mobile applications can scan the beacon. If I flash the "Sensor Demo", i...
Hi,I have two stm32f103 uc (as the slaves) which communicate with a stm32f407 (as the master) through SPI. I realized when SPI in both slaves are enabled the voltage on MISO pin drops to 2.5 Volt while when only the SPI in one of the slaves are enabl...
