nRF + LIS3DH board. I need to reduce current of the nRF advertising. I want to stop the nRF advertising and use LIS3DH to trigger restarting. Can I have the LIS3DH to monitor accel data and wake up nRF when reach a threshold? I know I can have nRF co...

I have a board that uses LIS3DH. Unfortunately I find the SDO/SA0 pin does NOT wire to VSS or GND. In this case, what would be the Slave ADdress(SAD)? In the spec it says 001100xb and the 'x' is either 1 or 0 when connected to VSS or GND. But no clu...

OK, thanks a lot. Let me look into these. Take care,

I understand we can have lis3dh to change the registers, but how can we let the nrf 51822 knows the lis3dh registers change without using i2c? So far my knowledge is that we can only read lis3dh registers through either i2c or spi in nrf 51822, and b...

Thanks. Sorry, I used nRF 51822 and 52810. I am not also much experienced on the embed development so if you could please provide more details will be much appreciated. For example ,some reference code or sample. Thanks,

Thanks a lot. So how the nRF to know the registers change? Reading it through i2c? You know that's more current consumption. Can you please share more about how the program the nRF to be waken on the rising edge, without using i2c timely reading regi...

LIS3DH. Can I use it to wake up nRF devices in an active way?

Sensor: LIS3DH. If I wire the SDO/SA0 to VDD, as pointed in the attached picture, will it cause any problems while using i2c? I currently can't READ and I am trying to identify the problem. Thanks,

(LIS3DH) What will be the slave address if the SDO/SA0 neither wired to VSS nor GND?
