Auto Reconnect
It has been requested, that there should be an automatic reconnect when the connection has been lost. This functionality has been implemented both on the A2DP Source and the A2DP Sink.
I am not convinced that this is a good thing in all the cases, so I suggest that you explicitly specify if you want to have it active or not with the help of the set_auto_reconnect(bool active,bool afterNormalDisconnect=false, int count=AUTOCONNECT_TRY_NUM);
method.
To open a Sink the code would look as follows:
#include "BluetoothA2DPSink.h"
BluetoothA2DPSink a2dp_sink;
void setup() {
a2dp_sink.set_auto_reconnect(true, false, 1000){
a2dp_sink.start("MyMusic");
}
void loop() {
}
The default value for AUTOCONNECT_TRY_NUM is 1000. After the system tried unsuccessfully to reconnect, it will stop to retry and you need to start the connection from your Bluetooth Source (e.g. Mobile Phone) again. During this time it will be possible to open a connection from another Bluetooth source (e.g. phone).
When onNormal
is set to true, the system also tries to reconnect after some normal disconnects. This is rather agressive - but matches the legacy behavior. If you just want to reconnect on signal loss set the value to false!
You can deactivate the automatic reconnect with:
#include "BluetoothA2DPSink.h"
BluetoothA2DPSink a2dp_sink;
void setup() {
a2dp_sink.set_auto_reconnect(false);
a2dp_sink.start("MyMusic");
}
void loop() {
}
Currently only the a2dp_source.set_auto_reconnect(bool)
method is supported w/o any additional parameters
