Flashing ble_app_uart_Mesh to a nRF52832 custom board, it does not advertise.

[shinho]

1. Development Enviroment

o SEGGER Embedded Studio : Relase 3.34

o SDK :  nRF_SDK_15.0.0  / Mesh_v2.0.1_src / s132_nrf52_6.0.0_softdevice

o Windows 10 Pro

o Chip : N52832 QFAAE0, Crystal 32MHz, 32.768KHz

o Development Board : PCA10040 (1.2.4)

2. Test Application

o Test Application : ble_app_uart_Mesh_SDK2_0_1.zip

o Related URL :https://devzone.nordicsemi.com/f/nordic-q-a/29108/how-to-add-mesh-into-nrf5-sdk-v14-1-v15-ble-application

3. Symptoms

o Build and Run on  DK board with Segger Studio : Advertising is normal and functions are all fine.

o BUT

   When Flashing  ble_app_uart_Mesh  to a custom board with nRFgo Studio or nrfjprog program, the custom board do not advertise,  it is not shown in nrfConnect scanner.

   However, example ble_app_uart in the ble_peripheral folder program works well  advertising on custom board. 

   What is difference ? 

 

  I tried many ways to solve this for several days, I could not resolve this. I produced custom boards and have to flash applications. 

  I need help and any tips or guides.

Hi,

Have you tried any other BLE examples?

Does that too has got issue with advertising?

You haven't mentioned anything about the antenna design.

Hi Shinho,

Please make sure you do a full erase of the chip before you test. There could be a problem that you have something in flash that the flash manager couldn't recognize and complain. Also please check the RTT log , you may have more information why the application didn't run. 

Anyway please use our latest SDK v2.2.0 we have a stock example of concurrent ble_app_uart and mesh.

Hi hari911,

I solved this issue by removing prinf(). Bur I am not sure why this causes problem.

In the main.c, I added   printf("\r\nUART started.\r\n");  instead of using NRF_LOG_INFO().

During debuging the source, it works fine. But when flash to custom board, it makes advertising problem.

After removing the printf("\r\nUART started.\r\n");, everything is working normal.

------------------------

mesh_main_init();

~~

// Start execution.
// printf("\r\nUART started.\r\n");
NRF_LOG_INFO("Debug logging for UART over RTT started.");
advertising_start();

mesh_main_start();

  // Enter main loop.
for (;;)
{
idle_state_handle();
}

---------------------

Thanks.

Hi Hung Bui,

I solved this issue by removing printf in main.c. I don't know how it is solved. 

I will check SDK v2.2.0. 

Thanks.
