Thanks for the information Robin. I will look into a try/catch block.

Rather than looking for an error is could I query the BLE and make use of the following information the puck sends?

Sorry if this is total newby question.

puck.js:406 Connected
puck.js:406 SEND ERROR: NotSupportedError: GATT operation failed for unknown reason.
puck.js:406 Disconnected (gattserverdisconnected)

Hello all,

I am a newbie and appreciate any help. I have tried generating a solution but have lost much hair trying!

I connect to the puck from a Windows browser using the following javascript function and query the accelerometer with a timer using the subsequent function. How can I detect if the puck.js disconnects?

Thanks in advance,

Jeff

// When we click the connect button...
    function connectclick() {
      Puck.write('Puck.accelOn(1.6);\n');
      Puck.write('NRF.setTxPower(4);\n');
      acceltimer = setInterval(accelcollect,650);
    }

    function accelcollect() {
      Puck.eval("Puck.accel()",function(x) {
        //Get accel data
        accel.x=x.acc.x;
        accel.y=x.acc.y;
        accel.z=x.acc.z;       
      })
    }

Hi Gordon,

I flashed firmware 2v09.90 and all is good. I do not remember the Web IDE telling me the firmware was out of date. I should have noticed I was downgrading the firmware. Great product and amazing support.

Hi Gordon,

Thanks for the help. I bought it from Espruino.com with Order ID: 4596 on 10 June. The Puck.js says 2.1a and a picture is below. Curiously when I first flashed the Puck.accelOn(), Espruino Web IDE gave appropriate values for accel and gyro. Now Puck.accelOn() gives Uncaught error: Not available on Puck.js v1 as shown in the screenshot below.

Thanks in advance,

Jeff

Hello,

Newby here with a new Puck.js , flashed to 2v09, and battery pull rebooted.

Espruino web IDE shows HWVERSION as 1 and which generates "Uncaught Error: Not available on Puck.js v1" when at HTML line

Puck.accelOn()

How can HWVERSION be updated to 2?

Thanks in advance, Jeff
