Problem with NRF51822 BLE Examples

Lukasz

Hello Everyone, I am trying to run examples of BLE Pheripheral in my NRF51822 board but something is wrong. SoftDevice and algorithm are downloading well but bluetooth is not starting.

Waitng for you answers, Lukasz.

    There is a big difference between running code and poking some bits in a GPIO register and doing BLE with a softdevice.

    The main reasons that people can't get the BLE examples working are:

    1. Fail to load a softdevice of the correct version for their SDK, solution and chip.

    2. Fail to set the ROM, RAM settings correctly in the Keil project. These are always listed in the Softdevice notes and may not be correctly set in the example.

    3. Fail to specify the RTC parameters correctly so that the Softdevice can start.

    4. On custom boards a common problem is messed up 16/32MHz crystal (depending on nRF variant).
