Rumble allows the sharing of messages and pictures without relying on the Internet, in a Delay Tolerant Fashion following the Store-Carry and Forward paradigm
If wifi is connected to an AP it should remain like that but if not connected it should cycle between 'Rumble' open AP and client mode for short intervals (maybe a random time between 1-2 minutes) to maximize chances to link to another Rumble peer and exchange a batch of messages. When in client mode, the handset should connect automatically to any 'Rumble' wifi which is open.
When turning to AP mode, disable 3G/4G data temporally to prevent abuse but allow the exchange of messages. Cutting internet access for short time shouldn’t affect other messaging apps too much. A small random time variation prevents two devices from being accidentally synchronized a never connecting to each other.
If possible, when leaving AP mode restore previous AP configuration (Wifi hotspot name and encryption/password)
