ble_app_hrs not working

[Ferhat B]

Hi

Im trying nrf52832 with 0 BMD-350 Evm. Working with IAR, nRF5_SDK_13.0.0_04a0bfd.

I need ble_app_hrs_pca10040_132_uart working properly. Seem like there is a main clock problem. Its hanging while init steps.

I loaded s132_nrf52_3.1.0_softdevice. I loaded heart_rate_demo.hex and its working. blinky_pca10040_s132_nrf52832 working fine.

Hi there,

I impelement uart to ble_app_hrs_pca10040_s132. I Worked on pca10040 demoboard. But when i debug same source on my board. It stacking in ble_stack_init(); step below;

ble_cfg.common_cfg.vs_uuid_cfg.vs_uuid_count = 0;   //HERE
err_code = sd_ble_cfg_set(BLE_COMMON_CFG_VS_UUID, &ble_cfg, ram_start);
APP_ERROR_CHECK(err_code);

Exactly same problem was happening on Evm board with "ble_app_hrs_pca10040_s132_uart" application. Is it about code size. How can i solve. Im so close to achieve my demo.

Do you have an an external 32 kHz crystal on your Rigado BMD-350 board?

As a note; its Rigado BMD-350, demo and my design.

No but, rigado warn about that and i changed like below

// Low frequency clock source to be used by the SoftDevice #define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC,
.rc_ctiv = 16,
.rc_temp_ctiv = 4,
.xtal_accuracy = 0} // accuracy ignored when using RC

[Sigurd]

Your LFCLKSRC looks correct. So if you have done any modification on the example code, the allocated RAM for the SoftDevice could be too small. Take a look at this post on how to configure the memory regions and find the correct RAM size.

I tried without modification, result same.
