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.

Do you really think that with such poor description there is any help for you???

Ok, I am trying to run ble_app_beacon example. My board is good because I can program the GPIO, now I want to use BLE in my board. First of all I want to use examples. Everything was compiled and download to board but nRF Connect app can't see my board. I am using Keli uVision.

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).

And if you are new to this you should start with the precompiled versions of the examples that include the SD. These always work on the DK's. This way you can get that feel good moment that the hardware works before you go back into Keil and break it.
