UART Program not working with custom board

[DD_]

Hello,

   I designed custom board using nRF52832. BLE Blinky code is working after uploading. I can able to see my ble with NORDIC BLINKY app and I can control LED. But while uploading UART code I didn't see BLE in UART APP of nordic. Please help me regarding. Thanks.

Hi, 

After further evaluation, I've decided re-open this ticket and close all other tickets that you have created on this issue. Keep any information regarding this issue to this ticket.

Regarding your issue. 

I would assume that the HW is correct, if other BLE examples work such as the BLE Blinky and you can see that it advertises. Is the ble_app_uart example completely unmodified? Did you change the board file?

Which UART app are you using? nRF UART or the UART console in the nRF Toolbox?

Hi,
 I didn't change any board file. The custom board we recently designed work well with BLE Blinky. Only BLE UART is not working. I tried using nRF UART and nRF Toolbox app. In both BLE is not showing.

Hi,

And the example is completely unmodified? Could you use a debugger and see if the application asserts during run time? Could you also see if you see the issue appears on other samples?

Hi,
While debugging I got breakpoint error. I am sharing that please see. Kindly have a look and respond asap. Thanks.

Hi,

So you're getting an assert in the UART event handler, which would explain why don't see the board advertising. Are you sending any data? Could you try setting a breakpoint in the handler and see exactly what function call that causes it to assert? 

My guess is that it asserts here:

Could you verify it by setting a breakpoint there and see what the error code is.

 You have to change the board file to a custom board file so that pins are mapped correctly.

Hi,
 I don't know why breakpoint is coming. I didn't send any data. I am only trying to advertise Bluetooth with BLE UART code. I am using reference design from NRF52 series. Then I need to change custom board file. I am attaching schematic too. Please help us regarding. Thanks.
