NRF52832 does not disconnect to phone

Question

Hi, 
 currently having problem connecting a second device to my BLE device after disconnecting the first device. upon further checking, i noticed that the first device is still connected based on the bluetooth list in settings of my phone. i am using nrf52832 with SDK 17.1 and nrf Connect for mobile (iOS).

Hello, 
 I see. Perhaps the bonding is not properly disabled in the nRF application? 
 What could happen is that if they are bonded, and you disconnect by pressing disconnect in the nRF Connect for iOS app, then the device will go back to advertising, and since the device is bonded, it will reconnect very quickly. 
 However, if you power the nRF device off completely, there is no way that it is still connected (after 4 seconds). If you still see it in your phone's settings, then that is not the list of active connections, but bonded devices. If you press the little (i) next to the nRF's name, you should be able to select (forget device), which should make it forget about it, and stop trying to connect to it. Hence, you should also not need to change the MAC address. 
 
 If this isn't correct, I am happy to test what you are seeing. If possible, please upload an application that can reproduce the issue, then I can give it a test run, to see what's going on. 
 
 Best regards, 
 Edvin
