BLE using PCA10005 and NRF51822-AK

[Marcio Segura]

Someone has a working source code (can be Keil format) for the PCA10005 and/or nrf51822-AK (China made) board? I tried the sample at "\nrf6310\s110\ble_app_hrs" but it seems to freeze or are not well configurated, stopping in the debug mode to a wrong state. I could see a ble device in the sniffer (PCA10000) when using Texas ble CC2541 but never with PCA10005 and nrf51822-AK.

May be you can try this (nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\s110\ble_app_hrs)

but sdk_v5.2 sould be use with softdevice v6.0(need nrf51822 version QFAAFA QFAAGC or QFAAG0)

nrf51822-AK use the nrf51822 QFAAC0 (you can see nrf51822 compatibility matrix in nWP-018 page5)

if you use softdevice in QFAAC0 may cause link down sometimes.

good luck

I'm not going well with nRF51822. Using the PCA10005 (QFAAG0) and \nrf51822\Board\nrf6310\s110\ble_app_hrs software, Softdevice v6.0 the debug in Keil I get freeze as attached image.

Gootoomoon, I wrote your *.hex direct using nRFgo Studio and a ble searcher in my smartphone but it didn't appear. I did the same with Texas Sensor Tag CC2541 and it was found by smartphone.

please check your ble_stack_init(); in main()

make sure your board has 32.768k crystal for your LFCLK

or you can try RC for LFCLK like this

static void ble_stack_init(void)
{
	uint32_t err_code;
	SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION, true);
	err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch);
	wk_printfn(WK_DEBUG_LEVEL_ERROR, "softdevice_ble_evt_handler_set, err_code=%d", err_code);
	APP_ERROR_CHECK(err_code);

	err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
	wk_printfn(WK_DEBUG_LEVEL_ERROR, "softdevice_ble_evt_handler_set, err_code=%d", err_code);
	APP_ERROR_CHECK(err_code);
}
