Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I would like to discover and connect peripheral devices with Bluenrg-ms central role. My initializing function set up public address with ac_write_config_data and than init gatt layer with gatt_init function. Finally i call gap_init with the followin...
I created new project with 32L152Discovery and additional Software STM X-CUBE-BLE1 5.0.0;After build I have a error "undefined reference to MX_BlueNRG_MS_init and Process.But in my project there are all files.
Hi community !I tested BlueNRG-2 generic ON/OFF model with other type of card with Mesh compatibility with which i can send what i want. When i'm sending a 2 bytes message like 01-00, DL3 (LED 3) switch ON which is normal. When the message is 2, 3 or...
I want to read from a Host module which is transmitting data using CP2104 chip. I have STM32F429 MCU, and I need to read data from that application using my MCU instead of VCP on my PC . I have not received any data by Configuring the MCU as UART (UA...
Hi,I'm trying to use the ST33 Arm-based TPM connected to a Raspberry Pi 3 (STPM4RasPi) but there is an error on the initialization of the TPM. I have a kernel NULL pointer dereference which prevents the TPM to start. I used this documentation https:/...
We designed a board using BlueNRG-2 and we uploaded the GPIO demo code available in BlueNRG-2 navigator (to toggle DIO14) to the board using the BlueNRG-ST- Link utility. The board didn't detected with high Frequency(.9MHz-4Mhz) so we changed the SWD...
Hi,I'm going to use SPBTLE-1s for comunication between PC and uController over bluetooth (SPI->SPBTLE) in a new project.Is it possible using SPBTLE-1S without programming (buy and mount it) or is it necessary to program it before ? Do I need to have ...
I am need to change the authentication requirements on the fly based on who is connecting to the device.
SCL mode is Fast Mode but i.e whoes speed is 400KHz. but when i see in logic analyzer its shows 350-360KHz. Why its fluctute .
