2018-10-22: This is a temporary repository to fix issue mbed OS issue 8344. I'm reverting to an earlier mbed revision that isn't messed up. Expect mbed to fix the linker issue in the next release and I'll remove this repository. I havne't tested the code at this revision - sorry!
Dependencies: BLE_API mbed mbedtls nRF51822
