I have some devices
1. running the same B4A app
2. in the same wifi network
3. Physically nearby, within 5 meters radius
4. periodically, using a timer with 1 minute interval, update their screen display by retrieving data from the remote mysql database to pick up the changes made by other users.
This works fine most of the time. However, from time to time, when a user makes some particular change, I want this change to be reflected immediately, instead of waiting for the timer event, on other users' device.
Could someone kindly give me some guidance, please.
TIA
