Bluetooth doesn't work on own created PCB

[TVB46]

Hi,

I make my first project with the nRF52832.

On my first pcb the bluetooth works fine, but this pcb was not fully assembled. 

Now i have made a second pcb that is fully assembled.

I can program the softdevice in the nrf52832 and verify it.

Then i  load the ble_app_uart example on the board, but i can't find the device.

i thought that it was a software problem, so i tried the ble_app_hrs example.

But there's still no connection found.

What could be the problems?

Hello!

Do you have differences between 1st and 2nd revisions of PCB in antennae part? 

Have you designed your PCB as it described in reference layout or you have your custom design?

Hello,

It's the same pcb, so i don't now why this doesn't work.

It's almost the same like the reference layout. The only difference is that i use the 'antenova sr4w035' as antenna.

You can try to solder passive components of antenna part from first pcb to the second. Also i recommend you to take a look at quartz resonator (its accuracy and loading capacitors). 

I believe you double checked all connections and your chip is soldered well

What is the spec of the crystal (tolerance and CL value) and the value of the load caps you're using?

The problem is solved. There was something wrong with the nRF52832. After soldering a new chip the problem was solved.
