Sigh. You are right of course. I had tried (and failed) to use an oldish Android phone to connect. And gave up. Then got it working on a little Android tablet .. but exhibiting the behaviour above. And actually the same behaviour in various BT tools on my iPhone.

It turns out that the original, failed, old Android phone was still up to something. Presumably connecting.

This is why the power-cycle/timing thing worked some of the time .. I was beating it (old phone) to connecting. Switching off old phone has cured problem !

Sorry to waste everyones time !

Hmm. Thanks!

I think I have a different situation .. Once Chrome cannot see the Puck, that's it .. I have to pull the battery and try over again. Once I do get paired, and connected it's fine. But if I then disconnect (in the ide) and try to pair again, I get the "https://www.espruino.com wants to pair with:" and "No Bluetooth devices found. Re-scan."

Hitting Re-scan will not find anything, unless I power-cycle the Puck, in which case the device appears almost immediately. If I hit "pair" quickly, it pairs and usually connects, but sometimes stalls on connect, in which case power-cycling usually sorts it ..

Odd.

Hi, I am having intermittent success getting mine to play nice at the moment.

Booting with switch pressed - passes self test.
Booting no switch - brief red flash.

Using LightBlue Explorer .. I see the Puck advertise itself as Puck.js 5f19 but only briefly (few seconds) before it disappears. Consistent behaviour on reboot.

WebBluetooth enabled on Chrome fine. I generally get "No Bluetooth devices found, Re-scan". If I re-scan and I am quick enough, I can then see the device, pair with it and connect successfully - and it works just fine. But the timing is pretty finnicky. I can miss the pair, or get the pair and miss the connect.

Is this expected behaviour ?

Thanks

Pat

(p.s. fab device, as usual !)

Ah ! Nice to know what was going on, thanks.

And of course it just works now :)

Thanks ever so .. blindingly obvious now that you point it out, but was definitely working in that form, for some reason, on a previous version.

Thanks a million.

I have been running this little program for months just to display temperature ..

var lcd = require("HD44780").connectI2C(I2C1);
var ow = new OneWire(B13);
var temp = require("DS18B20").connect(ow);
	
function onInit() {
	I2C1.setup({scl:B6, sda:B7});
	
		
	setInterval(showData, 5000);
}


function showData() {
 lcd.clear();
 lcd.setCursor(0,0);
 lcd.print("Current temperature:");
  
 // Get the temperature
 var t = temp.getTemp();
  
 // Round it to the nearest 0.1
 t = Math.round(t*10)/10;
  
 lcd.setCursor(0,1);
 lcd.print("Temp = " + t + " C");
}


onInit();

I updated to 1.69 just now (actually not sure what the previous version was) and see this .. which means little to me :( Can anyone here tell me what might have broken and how to fix ? I've swapped the LCD for another, but the same problem ...

Ditto. All working for me and definitely more reliable than cc3k IMO. You do have to use the special WZZnet build, though. Could that be the problem ?

Well, something magical has happen on 1.63 Wiznet .. this code now works perfectly ! I can switch the onboard leds on and off from a little web page !

E.enableWatchdog(10);

var eth = require("WIZnet").connect();
eth.setIP({ ip : "192.168.254.248" });
eth.setIP({ dns : "208.67.222.222" });
eth.setIP({ gateway: "192.168.254.100" });
