BNRG2A1 Terminates connection before reading service characteristics

I am using the STM32 NUCLEOL476 with a X-Nucleo-BNRG2A1. I opened the example project for Central Device. The board scans and finds the BLE device. I can select the device and it will connect to it. Then it reads the Service then terminates. I have t...

What happens at the receiver output of ST3485 when A-B is 127mV?

I have a circuit with ST3485 supplied at 3.3V. There's a 1.5k pull-up on A, 1.5k pull-down on B and 120R between A and B. So when the transmitter is disabled, A-B=120*(3.3/3120)=127mV. I'm wondering what happens at the receiver and if its output is s...

I am using v1.2.0 of the BlueNRG-LPS navigator. I am trying to run a BLE Beacon example on a STEVAL-IDB012V1. I don't see the device appear on a generic scanner I have. I have had success running other BLE examples on this eval board, but not the ...

Hello, I get a sensor STEVAL-STLKT01V1 and I upload the Unicleo-GUI application found on the website ST.com. When I launch the application, it recognize the sensor but I don't have the button of the different acquisition on the center of the screen.

What type of modulation is used in STISO621? OOK or edge triggering seems to be the two most commonly used in the industry.

"no device detected" in BlueNRG GUI, using X-NUCLEO-BNRG2A1

Hi, I use a X-NUCLEO-BNRG2A1 with a NUCLEO-L476RG .I try to use the BlueNRG GUI for the Virtual_COM_Port application. I copy directly the binary file into the "NUCLEO" device. But when I open the Port on GUI, it is displayed "no device detected" then...

Clock division and duty cycle for ST8034P

In the Data Sheet for the ST8034P the following is not clear about the ST8034PQRwhen the CLK output is active, does fCLK = fCLKIN or fCLK = fCLKIN/2 ?assuming fCLK = fCLKIN: is there some duty cycle (or other characteristic) to be met on the CLKIN in...
