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,

The ble_app_hrs_pca10040_s132_uart is for serialized application using UART as the transport interface. Instead you should use the ble_app_hrs_pca10040_s132 project.

Edit: There is a bug with IAR version 8 with the nrf_delay_us() function. See attached patch in this answer.

The ble_app_hrs_pca10040_s132_uart is meant for your application board and does not need the SoftDevice. You will need to port the serialized application to the application microcontroller in your system.

On the nrf52832 (Rigado BMD-350)(connectivity board) you are supposed to flash the softdevice + connectivy hex, for uart this is located in the folder

<SDK_InstallFolder>\examples\ble_central_and_peripheral\ble_connectivity\board\ser_s13x_uart
