Project Zip: beacon_lis2dh.zip
Following is my setup:
- Board : NRF52832 by Sparkfun(Link) - Added pull-up resistor for TWI
- Sensor: LIS2DH12(Custom breakout)
- IDE: Segger Studio
- Power Supply: 3.3V 1A
Project Goal:
- Beacon mode that switches between predefined UUIDs at regular interval or at an event
- Interface with LIS2DH and pass the x, y, z values in MAJOR, MINOR for the specified advertising UUID
Problem: The device can read lis2dh sensor (I am not sure if the readings are correct. I would like to request for help here). The Beacon advertisement is also working as the way as it should. After running for few seconds, advertisement stops and sensor reading also stops with ERROR 4. Given below is the debug log.
Note: LIS2DH library used is the default one that comes with SDK_17.0.2 found at ../components/drivers_ext/lis2dh12
