Working on nRF51822 QFAB custom board.

I loaded nRF51822 Beacon v1.1.1 Precompiled hex file in custom board.

Keil 5 Uvision iDE 

Windows 7

But I loaded examples programs ble_app_beacon codes. But Crystal and Bluetooth is not enabled.

Please suggest is it hardware issue or software issue.

Hi,

The precompiled beacon kit firmware is configured to use the optional 32 kHz crystal oscillator. If this is not present in HW, the device will wait indefinitely for the clock to start, which is why you do not see any activity. You need to change the 32 kHz clock source by adjusting the call to SOFTDEVICE_HANDLER_INIT() in ble_stack_init() in <nRF51822 Beacon v1.1.1>\Source Code\nrf51_beacon\ble_app_beacon\main.c to for instance the following:

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION, true);

Thank s Einar Thorsrud,

I changed above instruction. but Crystal and Bluetooth is not enabled.

i compiled program. it is showing Zero errors and zero warnings.

But in nrf_delay.c  it is showing. delay also not working

But no errors showing after build process

[Einar Thorsrud]

OK. If not errors are shown during compilation, then we can probably ignore this.

Regarding the main issue (beacon not working): Have you done any debugging to try to understand what is happening on the nRF? Also, just to double check: have you remembered to flash the SoftDevice in addition to the application?

Hello Einar Thorsrud,

first I am not loaded any softdevice hex file(s110_nrf51822_7.1.0_softdevice .hex) in fresh nRf51822 board.

I loaded only nrf51822_beacon_app.hex

Without soft device hex file , nRf51822 will work or Not.

Please justify my  question.

how to  set memory locations in keil for loading the Soft device hex file (s110_nrf51822_7.1.0_softdevice .hex)

Hi,

I will answer as best I can, but I am not sure I understood them. If not, can you elaborate?

 The SoftDevice is the BLE stack. Any BLE application (such as beacons) need it, an will not work without it.

 To be honest, I don't know. But it is not important either. Just program it using for instance nRF Connect Programmer or nrfjprog.
