I have set up a scan for peripherals w/ a specific service UUID and asked for repeat delegate calls. This works fine in the foreground. (I get them about as frequently as the peripheral is pumping them out) However, even w/ "bluetooth-central" in my background modes, I only ever seem to get one call to the didDiscoverPeripheral: delegate method when the device is in range/turned on while the app is in the background. Is this the expected behavior? It seems as if CBCentralManagerScanOptionAllowDuplicatesKey is automagically set to 'NO' when in the background. I have found that if I walk out of range, then back in, I may get notified, but if I toggle the peripheral off for a while (a few minutes), then back on, I receive no callback. _______________________________________________ Do not post admin requests to the list.
