Anyone has st32f25a datasheet and kindly share with me?

How much time will the node work in the MESH network?

Good day!How much time will the node work in the MESH network, if it is powered from a 3.6V battery with a capacity of 1800 mAh? It is assumed that all nodes operate in standard mode and low-power nodes in the network are not used. Transmitter power ...

BLUENRG2 SPI slave mode issue (getting only the first byte of a frame)

Hello,I'm working on a BlueNRG2 device.I'm getting some trouble using the SPI in slave mode.If I configure the SPI with SPI_CPOL_Low and SPI_CPHA_2Edge configuration, I can receive from the master all bytes.If I configure the SPI with SPI_CPOL_Low an...

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...
