I'm using a BLE Nano (nRF51822) and I'm trying to read an accelerometer's X, Y, and Z coordinates over I2C and then write the readings to a connected android phone over BLE. When I include my I2C code (I2C init and accelerations available) my BLE Nano doesn't show up as a BLE device that my phone can connect to. When I exclude my I2C code, my BLE Nano shows up on my phone and I can connect to it but now there's nothing to send. Am I able to use I2C and BLE together? If so, how do I do this?
