I'm using the espruino tools npm package cli tool to connect to the puck.

Connecting with --port <MAC address instead of -d <deviceName> worked fine.

Thanks for the hint!

When puck is advertising it is not possible to connect it via bluetooth.

I use the npm espruino package on linux to connect to the puck and to upload code.

After uploading this file

const keys = {
  temperature: 0x1809,
  battery: 0x180f,
  someData: 0xfffe
};

function a() {
  digitalPulse(LED3, 1, 1000);

  const adData = {};
  adData[keys.battery] = [Puck.getBatteryPercentage()];
  adData[keys.temperature] = [Math.round(E.getTemperature())];
//  adData[keys.someData] = [1, 2, 3, 4, 5];
  NRF.setAdvertising(adData);
}

setWatch((e) => a(), BTN, { repeat: true, edge: 'rising', debounce: 40 });

it is possible to connect to the puck. Pressing the button to start advertisement does not change that.

When slightly modifying the code to

const keys = {
  temperature: 0x1809,
  battery: 0x180f,
  someData: 0xfffe
};

function a() {
  digitalPulse(LED3, 1, 1000);

  const adData = {};
  adData[keys.battery] = [Puck.getBatteryPercentage()];
  adData[keys.temperature] = [Math.round(E.getTemperature())];
  adData[keys.someData] = [1, 2, 3, 4, 5];
  NRF.setAdvertising(adData);
}

setWatch((e) => a(), BTN, { repeat: true, edge: 'rising', debounce: 40 });

to advertise on an additional service id will change that. Once the advertisement is started by pressing the button I am not able to connect to the puck until it is reset.
The behavior is not specific to this service ID.

Hi,

When the Puck.js is in bootloader mode EspruinoTools cannot connect to the Puck.js to upload the firmware.

Obviously it does not find it under the name puck.js xxxx, but it also does not work with -d 'DfuTarg' or -p <device address> or without a port or device option.

Uploading the firmware when the Puck.js is not in bootloader mode is also not possible (as expected)

I am running EspruinoTools under Linux Debian buster with bluez 5.50

Any help is appreciated.

Thanks,
Lars

PS:
I know there are other ways to upload firmware to the espruino devices. I am looking for a way to automate it without fiddeling around in a GUI tool
