pca20006 (nrf51822 beacon) ble_app_uart example

[John]

Hello, Exist an example of application ble_app_uart for pca20006?I found ble_app_uart for pca10028,but I want a project for pca20006(beacon) .I want use this project for receive data from tablet/smartphone.Exist another example of aplication that receive data from tablet/smartphone? Thanks!

@John: No, you would need to port the example for PCA10028 to the PCA20006. The chip are the same.

You would need to map the GPIO pins for button and LED accordingly. Also there is no 32kHz crystal on the PCA20006 board, so when you init the softdevice (SOFTDEVICE_HANDLER_INIT), you should use the 32kHz RC clock source.

Thanks @Hung Bui I mapped the GPIO pins for button and LED and I changed clock source in SOFTDEVICE_HANDLER_INIT to NRF_CLOCK_LFCLKSRC_XTAL_50_PPM but don't work.Must to change another things?

@ John: You should use NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION. NRF_CLOCK_LFCLKSRC_XTAL_50_PPM still uses crystal.

OK @Hung Bui,I change this but don't work,the beacon don't make advertising.I dont't know why don't work?

[Hung Bui]

@John: Please run the device in debug mode and add a break point in the application assert handler to see what could be wrong. You should check for err_code return from any call.

Thanks @Hung Bui, I solved the problem.I change IROM1 and IRAM1 from project and now it's work.
