"poweredOn"

由于iOS没有设备连上和断开连接的回掉，android有；所以统一要求中心设备订阅Characteristic。 那么didSubscribeTo表示设备连上，didUnsubscribeFrom表示设备断开。android端didUnsubscribeFrom会被触发2次，在设备主动取消订阅的情况下。

Library update needed

Hello!

I need to transfer a file from one BLE device to another. Both will be flutter apps. There's a lot of flutter libraries out there to act as a BLE client, but I couldn't find any library to act as a peripheral device except yours. But it is so outdated that it's not usable anymore.

Is there any chance you could work on updating your library? I'm willing to sponsor this project if needed. Please let me know what you think.

Thanks!

startAdvertising cannot be start for more than one time
My application had call startAdvertising and it is works,(both send and receive characteristic). But after that, after i called stopAdvertising and try to startAdvertising again, it doesn't work any more.(means can't send and receive characteristic) What can I do for this? Thanks a lot.
