GATT cache clear

Hi,

After completing an OTA firmware update to my device, the device restarts and iOS reconnects. If the GATT attributes change in the update, reconnection sometimes fails as iOS is using a cache of the attributes from before the update. Currently our solution is asking the user to turn Bluetooth off and on – not ideal.

Is there any way to force iOS to clear this cache? I can’t use the Service Changed characteristic (0x2a05) in the Generic Attribute Service (0x1801) as the service ‘changes' when the device is disconnected.

Thanks

Nick Brook
