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 .
I am trying to find out how to set up this as a master processor. I am trying to find out how to program it. Is an Stlink/V2 acceptable to flash it. I am not seeing a pinout on BLUENRG-M2SA for SWDIO and SWCLK. It is not supported by Cubemx ...
Hi guys,I need to add the Device Information (0x180A) service in the advertising phase.I tried to do that in aci_gap_set_discoverable function, but ever fails with error 0x42 (invalid parameter). Whitout service uuid list, works ok.So, I tried with a...
