Connection problem after initial connection

[GT]

Hello everyone,

I have a strange issue with s110 + whitelisting + Device Manager + nrf51822 + GCC and hopefully you can help me with a good advice. It appears that the device filters correctly based on the whitelist. However, the problem is that after already bonded device (Android Smartphone or Nordic Dongle) connects and disconnects to the nrf51822 this device can not connect again until another device connects/disconnects to the nrf51822. Basically the two centrals trying to connect to the peripheral have to take turns.

Any advises and ideas how to approach this problem are more than welcome.

Thank you in advance for your assistance!

@GT: I would need to have a sniffer trace to check if the issue was with the whitelist (establishing connection) or with bonding (re-encrypting connection).

Have you tried with our stock example ? the ble_app_proximity for example ?

Hello Hung, Thank you for the reply. I've already managed to solve it. The source of the problem was how I was handling the advertising module and more specifically starting and restaring it. Now, the application keeps track of the module's state and takes care to stop it before it request a start again. Works fine now.

@GT: I'm glad that it worked for you now. I guess the case can be closed.
