Device previously connected, reconnect or close for new device

Whenever I try to connect I get the error "Device previously connected, reconnect or close for new device". But there is no way to disconnect properly, and no way to find the address to actually disconnect from. And, I was never connected in the first place.

enable() does nothing, initialising turns it on but then hangs app

enable() doesnt actually do anything, only way to turn on bluetooth is intialise, this however then reloads the current form and hangs the app. Therefore the library will only work if bluetooth is already on before you load the app. I cannot get around this.

Apple App store now rejecting apps that use this extension

Since the UIWebView was deprecated and now forbidden, and the Cordova pod used by this app is based on UIWebView, any iOS apps using this extension will be rejected. It looks like Cordova has recently committed some updates to shift to WKWebView.

Add Peripheral Commands

I think that I can add the Cordova callback implementation for the peripheral commands in Bluetooth.java. I would also like to add a soft fail for commands that are unsupported on a particular platform; that is examine the result code, return true on success, return false on failure making the error response available for inspection, and throw an exception where required. Mr. Almog suggested that I file and issue and open a pull request. I new at this and I would like to contribute these suggested changes.

Missing methods

Hi,

there are some methods in the plugin thar are not available in the cn1lib. For example startAdvertising or stopAdvertising.

Build errors on iOS and app hangs on startup on Android

On multiple apps in development, after some builds, build errors (iOS)or app crashes (Android) begin. Initially, the apps were building and working OK, then after changing something not related to Bluetooth or JSON, builds begin failing. In the most recent case, the only item changed between a successful build and a failing build was changing the text on a UI label. Here is the iOS build error below, and the JSON extension has been installed since the beginning. The exception thrown on the screen when Android crashes is similar.

Won't connect

The callback for connect() is never called.

No call back from enable()

No call back from enable(). This means if bluetooth is not on and gets enabled, the app wont proceed and needs to be restarted, a call back would fix this nicely.

Can't Receive Text Data From BLE Device

I am currently running Android 11 and using this plugin. I can send text data correctly, but cannot receive any text data from a BLE RX/TX device. I am able to correctly "subscribe" to service, but it does seem the callback method is called when text data is sent from the device to the phone. Using another application I am able to both send and receive text data no problem to that service so not a hardware problem. I think it may be an issue with the Cordava plugin somewhere.
