Interface and connectivity ICs

We have been using the BlueNRG Tile in the STEVAL-STLKT01V1. The datasheet says there are reference design and layout details to implement our own circuit board. Where do we find the required information and what are the implications for compliance?

Sigfox require BPSK (D-BPSK), however, S2-LP provides only FSK derivates of modulation schemes. Can somebody explain the trick how the modulation scheme is configured on S2-LP to accommodate SigFox differential phase shift keying for uplink and downlink?

How to get all 27 bytes of payload in BlueNRG.

I have a custom primary service (in server role) with a R/W characteristic set for 27 bytes of data and GATT_NOTIFY_WRITE_REQ event mask. My android client app is sending a verified 27 byte payload to this characteristic. I only get events with 20 ...

I want to implement One to Many i.e. Broadcasting so that I can send the data from one device to 3 other devices in real time? I am new to this, please help me out and let me know how should I proceed to implement the same.

I am using BLENRG-MS for the same.

Is there a calibration example of a resistive touch screen?

Good afternoon eveyone​​We want to replace the conventional capacitive touch screen with a resistive touch screen. Capacitive touch screens do not require calibration, but resistive touch screens require a first calibration. I know there is a touch c...

Is there any way to force remote_port in tcp_pcb structure from LWIP?

Hello, I am using stm32F429zi as TCP server just like in the example project "echo server" and my application needs to responding every time on the same port, but after disconnect and connect to the sever it changes port. Is there any way to force re...

Working MESH network without a smartphone

I am trying to implement a working MESH network without the participation of a smartphone. The idea is to send messages from all test nodes to one specific node through the MESH, which has the same hardware structure as the rest. This node should pro...
