BLE Blinky example code not working on nRF52810

i think this problem is solved(Ble_blinky_led example, advertising led on is okay), i have changed the SEGGER Embedded Studio V6.30 to V5.62. But still, I didn't get a Bluetooth signal on my board.

yes, i changed the capacitor but still not working.

Thank you.

Hi Rahman,

From your schematic,

You have chosen the load capacitance as 12pF. But the crustal that you have chosen has a load capacitance of 15pF (datasheet of ASE-32.000MHz-LC-T)

The formula is C1 = C2 = 2 * C(load) - C(pin)

C(pin) is 4pF. So you should have the C1 and C2 approx. 26pF.

Hi Priyanka,

I use the development board's capacitors for my custom board. It's working fine. The problem was in my capacitor tolerance. 

Thank you.

Hi Rahman,

So are you able to get a Bluetooth signal  now?
