Reconnecting issues

[jkoenig72]

Hi,

try to use USB Host Shield with a Bluetooth dongle in combination with one of those cheep mini bluetooth controllers for my e-skateboard

Almost there - by using the PS4BT example plus a few minor modifications:

• want a fixed pairing. Just to one bluetooth address. Should not reconnect to something else. By adding the BT address to the main sketch and pass it through.
• Want to to shutdown is slowly in case connection is lost. I was expecting that PS4BT.connected() will do that, but I need to include another boolen var connected and simply make it public to check. Done.

Open issue is reconnecting:

void loop() 
{
  Usb.Task();

  //&& Btd.incomingPS4
  if (PS4.connected()) 
  {
    if (Btd.connected!=false)
    {
      Serial.print("Value: ");
      Serial.println(PS4.getAnalogHat(LeftHatX));
    }
  }  
}

How to do it? It works 1st time when Arduino starts (or when I reset the board). But when I switch off and on again the controller it does not successfully re-connects. As I said, it does when its reboots.

Then I detected that its the same - it ONLY works when I initialized with

PS4BT PS4(&Btd, PAIR);

In contrast

PS4BT PS4(&Btd);

Does not work. Debug out is

HCI Disconnected from Device
Wait For Incoming Connection Request
Keyboard is connecting
Class of device: 00 05 40
Incoming Connection Request
Remote Name: MOCUTE-036_B53-70E8
Connection established
Connected to Device: 16:07:15:03:70:E8
Received Key Request
Wait For Incoming Connection Request
HCI Disconnected from Device

Any idea?

Please do not open up multiple issues. Please stick with the one you have already opened: #321.

Regarding your request for only connect to a fixed Bluetooth address, then there is already a issue open for that: #261.
