NRF52832 Custom Board BLE working but BLE does not send data.

[Nisubaba]

Hello 

I am working on BLE custom board NRF52832 design. I have made 3 PCB for it and out of three, 1 PCB working fine and rest of the two connects with the BLE but doesn't send the data. I have checked the design and the program, also I have checked the crystal which is working fine but my controller can not be able to send the data. My custom board can not be able to transfer the data over the BLE. BLE advertise perfectly.  

if any one can help me in that. it would be great.

Very little to go on there.

So what debugging have you done to find what's happening?

In particular, to see what's different between the one that works, and the two that don't ...

For debugging i have checked on serial. Data available on serial. 

I have also checked first board and compare it with second board but there is no change. I have changed nrf52832 controller twice but still ble can not send data. 

Nrf52832 advertising and gets connected to other ble device but didn't send the data.

I have also checked on nrf connect application. In which ble gets connected but data value was not displayed means data didn't send by ble.

I have also replace both crystal but still did not get any result.

So use the debugger.

You will most likely need to use Monitor Mode Debug:

Hi,

Could you upload the:

• Schematics
• Datasheet of the HFXO and LFXO crystals that you're using and the full part number of the crystals. 

I can make the case private first if you prefer it
