Interface and connectivity ICs

I am trying to communicate with the VCNL36887S via i2c using the STM32F407VGT6 I am able to read the output register 0xf2. However am unsure if I am writing to the registers correctly as they are not impacting the output results as expected.

Please see files attached:Data/application Guide of VCNL36887SImages of function used to read from the output registerand an image of how I am attempting to write.I will also include my code from Keil and CubeMXAny advice would be appreciated Best R...

How sent Notification from peripheral to Central using Stbluenrg2msp

Hi I using bluenrg2 m2sp chip as pheripheral role and st ble sensor App as a Central , i need to sent notification from peripheral to Central whenever event occur , con you share information , which api i need to use in order to sent notification fro...

I'm using the "SampleApp" and "Beacon" BlueNRG demos. I have one master and two slaves. The two salves should be in sleep mode except when they send data. I need data transmission every 50ms on each slaves. What is the best way or example to achieve it?

We need to have as most is possible a constant communication between the master (data receiver) and the two slaves (data senders). The data sent by each slaves should be around from every 20ms to 100ms. So the receiver would receive data every 10ms t...
