After Android phone cancel pair, can not connect

[Chaw]

Dear NORDIC I have one strange issue:

My nRF52 app work well, then I use Android phone connect to it, it's OK. Then Android phone cancel pair, so nRF52 disconnect,

then Android phone can search nRF52, but can not connect successfully,

Android phone show "nRF52 refued" or "can not communication to nRF52".

Then, I use ble_app_template(SDK12 example), foud that it is same. Could you help me check why?

Hi Chaw,

What do you mean by "cancel pair" ? Was that you clicked pairing and then you canceled it ?

Have you tried to use nRFConnect app to connect and pair ?

Could you record a sniffer trace ?
