Hi,

We solved the issue by using internal RC oscillator with 30 ppm accuracy.

BLE start advertising in other ble devices.

Thanks & regards

Hi Nguyen, I changed the clock form crystal to RC, still ble is not working.

Ah, in that case you need to change the Softdevice init to use RC instead of the crystal. You can find the define setting in sdk_config.h. It is by default using crystal.

Hi AndreasF,

I am using segger embedded studio for debugging.

Code is working fine.

I increased the TX power also. But ble is not advertising.

Now how can I debug it?

Hi, thanks for your quick response.

I will try to debug it.

But I have a doubt, how the code is working fine in thingy?

If there is a problem in code means, then it won't work in thingy also. Am I right?

One difference between my board and thingy is, I am using internal RC oscillator instead of external 32 Khz Crystal.

Thanks & regards,

Hemabas

Hi.

Can you try to debug by using Ozone?

Ozone is free to use.

Best regards,

Hi, I tried experimental_ble_app_blinky example.

I dont use any IDE, so I am unable to debug it. I compiled the code with the help of gcc and the code is working fine in thingy, but it is not working in my board.

We checked the frequency in spectrum, frequency is detected. But board is not advertising. If I am missing anything?

Hi.

Which example did you look at? Have you tried debugging?

Best regards,

Hi andreaf, I flashed softdevice s132_v4.0.2.hex in my device

Hi.

Have you flashed the SoftDevice to your device?

Best regards,
