LIS2DH interface with Nrf51822 reading FF values in custom board

[Ketan Bhaid]

I am interfacing LIS2DH with nrf51822. I am using 12.3.0 SDK and 130 V2 for development. I have successfully interfaced LIS2DH eval board with Nrf51822 eval board (waveshare BLE 400)

When I try to run the code on my custom board with exact same connection I am getting all values as 0xFF. earlier I thought the soldering of LIS2DH is not proper but I tested with more that 20 boards but in all board I get values as oXFF.

can someone help me out to fix the issue.

If you're using the LIS2DH with the I2C interface, you're probably missing the pull up resistors. Enable the internal pull ups or use 4.7k or 10k external pull ups.

Can you post the schematic and layout (gerbers)?

Are all other features of your custom board working properly?
