Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Is it possible to use the BlueNRG API to have a automatic characteric broadcasting? Currently I do this manually by calling the functionaci_gatt_update_char_value()for the corresponding characteristic but that's kinda cumbersome. Does the stack provi...
Hi,we made a board with the same components as the ST75MM demoboard, but we have a strange behavoir. Without signal on the IN+ of PA, we have a saturation (square wave) at the output of PA. Is there anyone who can help us understand why there is this...
Hello,I am currently facing an issue while interfacing through SPI from a TI RM46 Hercules lockstep processor to the M41t94 RTC. The issue is that no matter what data or settings I send to the RTC, through an oscilloscope it just shows the in/output ...
Hi,I recently bought 2 evaulation boards (stevalidb011v1) to check BlueNRG-LP working mode.I run built-in sw and seems it works great even at long distance.I pretty new in BlueTooth technology ( very new :) ) , so I wonder if there is any documentati...
Hi, I'm doing the development of the bluetooth communication between two bluenrg-2n devices. The bluenrg-2n are connected with stm32f405 through SPI. The two custom boards(GATT Client and Server) are identical. Now I have the problem when receiving d...
So, is there any solution existing to connect my own sensor with I2C bus to this board ?My "sensor" is a 15bits adc converter. I would like to send the values of the adc on the io-link bus.Do you know if it's possible ?Thanks !!
We are using STKNX DC-DC (12V) output for controlling relay.DC-DC output goes down to 4V after some time without any operation on KNX bus.Please suggest the solution.
The band supplied is 150-170MHz and I was wondering how hard and fast that range was.I'm going to do more research myself but if anyone knows or has used something similar that would be very useful.
Hi everyone,I'm currently porting SPIRIT1 example in order to carry out the basic implementation in my on board.I've configured SPI config this way:void RadioSpiInit(void) { /* SPI1 parameter configuration*/ pSpiHandle.Instance = SPI1; pSpiHandl...
The picture is the STM32WB55 microcontroller and the part connected to the breadboard is STEVAL-MKI179V1 with LIS2DW12 accelerometer.
