Unable to run BLE (app_uart) example application in nRF52832QFAAE11809AC revison 2

[IMRAN]

Hi, I have custom nRF52832QFAAE1 when I tried to run Peripheral applications which are working fine. whereas BLE applications are not running it seems.

here are the things I want to clarify:-

1) Using SDK14.1.0 and soft device 5.0.0.

So for the above SDK and Softdevice is the Memory allocations in LD file is correct or not.

MEMORY
{
FLASH (rx) : ORIGIN = 0x23000, LENGTH = 0x5d000
RAM (rwx) : ORIGIN = 0x20002a68, LENGTH = 0xd598

}

2)  Do i need to configure an internal oscillator to run BLE APPLICATIONS.

Attached schematics of my Custom board

Hi

Please see this whitepaper on antenna tuning. Specifically chapter 4.2 on Pi-networks. You can use the nRF52832 reference layout as reference.

Best regards,

Thanks for the info

We replaced nrf52832-QFAAE1 in the place of nrf52832-QFAAB0 in the nrf52 development board. we observed the basic code which controls the GPIO pins working fine, as well as we observed error code 0 in the ble_stack  _init() function and advertising_init() function which means BLE initialized and advertised fine but we didn't get the device nrf connect app so can you please provide some information about type of issue and the resolution 

thanks in advance.

After advertising_init(), I think you have to do advertising_start() to actually start the advertising?

Do you have RF test gear to verify whether it is transmitting anything at all?
