So I want to talk to the BLE eval kit ( STEVAL-BLUEMIC-1 ) with another microcontroller. I see that the on board BLE module (SPBTLE-1S) has a SPI and UART interface however the board itself only contains 5 SWD pins. These 5 pins are Vblue, SWDCLK, GN...

Is the design of this circuit OK to be USB HOST?https://drive.google.com/open?id=1zKJQuh5CJrl1X4RY4lJzdEwwPDz0wLm2https://drive.google.com/open?id=1pBKWj9IoOnVFrW1I-eUM-54Y8_F0gw5J
I'd like to read measurements from about 50-100 remote temperature sensors. I'm considering two options: BLE mesh with SPBTLE-RF modules and 6LoWPAN with SP1ML-868 modules. How many remote sensors per second can I read in both cases? I don't need exa...
I am using the ST BlueNRG-MS and would like to know the required procedures (documentation) in order to put on Bluetooth logo & able to sell globally.Anyone have done this for end product ?
Hello people, I need help for a University project. I'm trying to establish communication between 2 STM32F103 with a pair of nRF24L01. I am a complete newbie to programming MCU.I have tried a lot of libraries but none that I could compiled in uVision...
We are using the procedure defined in AN4491 to upgrade BlueNRG-MS firmware from 7.1e to 7.2c. Blue_flag erase (aci_erase_blue_flag), flash erasing and programming works but the aci_reset_blue_flag step is failing with response “0x4A: Blue Flag faile...
How to transfer audio files from the phone to a (BLUENRG+STM32+SDcard), without using additional software on the phone? I'm not sure, but I need an FTP profile. I need to realize the transfer of a sound file using the built-in Android / IOS functions...
I will attach you the circuit.It was just made looking at the datasheet and its pin configurations.Please go through the circuit and let me know for any modifications.Thank you.
