Hi,To measure distance between two bluenrg module using rssi value.The two devices are loaded with BLE_Beacon example with different public address and few scanning functions are included.Both the device advertising data can be seen in ST Ble APP in ...
I am currently using BLUENRG-M2SP Nucleo expansion board and STM32L476 Nucleo board. When I execute the aci_gap_start_observation_proc function, I get a 0x46 (BLE_STATUS_NOT_ALLOWED) error.Do I need to make any special settings when executing the fun...
Dear Sir,I kindly ask you what is the quiescent current value of the driver with EN=HIGH (chip enable) and Vs up to 24V; into the datasheet at page 8/14 is written 2mA max @ Vs<=14V, what should be the maximum value with Vs equal 24V?On page 10/14 is...
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.
