BLE connection issue

[SciTER Development Team]

BLE device(having nRF52832 chip) can not connect with mobile phone. for more information i have attach nRF Sniffer Log.

SDK: 14.2

Stack: S332_05_00_00  Multi protocol (BLE + ANT)

Mobile phone device: iPhone x(ios version 12.2), iPhone 6(ios version 12.2), iPhone 5 (ios version 10.3.3)

According to log, we can say that slave not respond to master for LL_VERSION_IND. Is there anything wrong with Master or Slave.

please give appropriate solution.

I assume you are using identical hardware here between the two. Then the only explanation I have is that the LFCLK may be on the very edge of tolerance. Please test with 500ppm yes.

Hi Kenneth,

I am using Single hardware for SDK12 and SDK14 Hardware verification.

I have test with 500ppm but got same result.

Please not same crystal setting work witj SDK12 is ok,but not work with SDK14.

Hi,

Is it possible that you have other on-going activities that may be interfering with the link?

For instance: Can it be that you are using the softdevice to also search or have open an ANT channel, and/or scanning/advertising a second BLE link?

hi Kenneth,

i have tried with ANT channel closed, then connection ratio improve by 40 to 50% but still issue not resolved.

Thanks,

Any way you can create a simplified program I may run on a DK to recreate the problem here?
