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

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

If you want any meaningful feedback post your pcb layout and schematic. Otherwise it is nearly impossible to debug as any number of things could be wrong.

If you dont want to do that then first thing to do is make sure it is on channel with a spectrum analyzer and look for one of the advertising channels. Max error is 40ppm.

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

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.

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?
