BLE error check

[Minseo]

Hi!

I am developing using ble.

ble works fine, but I'm worried it will freeze sometimes.

Is there a way to check errors in real time?

Thank you

Hi, 

You can use nRF Sniffer for Bluetooth LE to know what happened in the air and debug log from the device is also helpful.

Thank you for your reply.

Can I use it only for development kit or dongle?

Thank you.

Hi Minseo, 

You need the supported development kits or dongles running as sniffer to observe the application on your device.

Then, is there any way except sniffer?

I am developing without DK and Dongles.

Thank you.

You might need to print some logs to help yourself like add DEBUG into the processor parameter. 

Without a sniff log, it is hard to know what happened in the air.
