IIS3DHH accelerometer temperature drift

The datasheet reports an offset drift TCOff of max. 0,4mg/°C. We made temperature tests with 3 samples and found the offset drift beeing 0,17 ... 0,58 mg/°C so higher than allowed. Does this meet your expectations? Can you share your measurements? T...

I would like to know what device and model to use for an wireless application where I will have 1 stm32 as a master micro controller waiting to receive data and transmit data(two-way communication) from 5 slave stm32 microcontrollers.

The Master stm32 controller need to send talk with the particular slave in order to turn a LED . By using switch,i will turn off the led in the slave controller .The slave has to sent state of led to master controller .There will be cases when maybe ...
