run ble uart application with proper bootloader on a custom board

[liushu1314]

Hi,

I want to run the experimental_ble_app_uart application on our custom nRF51822 board.

However, I could not find a proper bootloader to start the application. Is there a general bootloader that I can use?

Softdevice: s110_nrf51822_7.1.0_softdevice.hex

Another question: I have the nRF51 Development Kit. Why the DK board does not required a bootloader to run the application? There are only two regions programmed on the DK which are application and softdevice. The DK board can run the uart application perfectly without any bootloaders. However, if only program the softdevice and application on our custom board, the board can not be detected.

Regards, Shu

@Hung Bui: I tried both. After programming the SoftDevice 8, I saw that the start address in the nRFgo was 0x18000. For SoftDevice 7, the address was 0x16000. My main problem is that after programming the SoftDevice 7 or 8 with SDK7 or 8 's ble_app_uart application, my board and Beacon Kit are not broadcasting BLE signals. However, the Development Kit board does broadcast.
