Yeah the phone stays connected ok it seems. At least enough to upload the sketches a few times changing the LED number.
Well this is an Intel Bluetooth module. (8087:0a2b) so should be pretty well supported. Restarting the bluetooth will show the puck again and connect but then it will drop after a while. I was repeatedly sending
Puck.getBatteryPercentage()and I did that for about 11 times every 2 or so seconds. Then I got to typing the the example sketchvar on = false;
=false
setInterval(function() {on =!on; LED1.write(on); }, 500);
Press Ctrl-C again to exitI literally got to the last char and then pressed return and nada. It became unresponsive so I had to Cntrl-C it.
I shall investigate if there are some tweaks for my bluetooth connection. Because it does seem whatever happened it has become worse ;)
Thanks for the help.

Yeah, well that seems to have gotten us a little closer. Look what verbose revealed.

Yes I did use Google Chrome on my phone. However after a restart of my phone it seemed to work. That is I was able to connect to it using Chrome WebIDE and upload the sample sketch. Which I have not been able to do for a while now. Trouble is it is VERY fiddly trying to type anything via the phone.
I have rebooted my laptop 'just in case'. No joy.
Ironically enough I did just install
npm install espruinothere are a few slight modifications you need to use for Debian though. The package is called nodejs as is the resultant binary. Still I did runsudo setcap cap_net_raw+eip $(eval readlink -fwhich nodejs)and that seemed fine. You then need to link node to nodejsln -s /usr/bin/nodejs /usr/bin/nodeHoweverespruino --listjust gives meespruino --list

No joy alas. Even with Chrome it does the same
.For the record I am using Debian 9.0 (testing) Kernel 4.12.0-1 and bluetoothd is 5.45
Like I say though, it is not just my laptop that seems to have problems keeping a connection my phone does too. A Samsung S7.
Now the odd thing is that before on an older firmware I did not seem to have such problems but of course that was a few months back so hard to say what has changed.
Anyway to debug BLE connections? I would be curious to know if it is the Puck dropping the connection or the computer.
Thanks.
-
Did the reset and seemed ok for a minute but then just disconnected again and went back to being erratic. What I find different is the fact I keep on having to hit pair with the device when it disconnects even though it is a saved connection. (you can see in the video is show it as (paired) but asks to pair again.
Not sure what is going on here. But seems the my phone is also dropping the connection to the puck not just my laptop.
Odd.
-
Yeah.. so changed battery managed to upgrade firmware to 1.93 now though I seem unable to connect to it.
Hmmm.
-
You may be right.. Not sure. But I see the green LED looks very weak. (see video) Would be nice if there was some way to determine the battery voltage externally. Hey ho.
Edit: won't let me upload the video. Here is a link to it instead.
-
Ok this is starting to get very frustrating. I have updated firmware before ok but for some reason now the puck0js won't stay in bootloader mode. That is I hold the button insert the battery release button and LED turns red. It stays red for about 10 seconds then turns off. Or if I am very quick and try to connect to it using nRF tools it will also drop out of bootloader mode.
What the hell is going on. I have not touched the puck in months (family issues to deal with) but I am pretty sure it was on firmware 1.90. I want to update to the latest 1.93 but cannot if I cannot get the damn thing to stick on bootloader mode.
Any ideas?
-
Or if you're interested in what's been done but not yet released, you can see it here: github.com/espruino/Espruino/blob/master/ChangeLog
Fair enough. Seems quite a lot of changes over last few months so it is important for people to upgrade to 1.90 asap.
Thanks.
-
Hi,
So I flashed my PuckJS firmware to 1.90 following the instructions given. Pity I had to use my phone to do it, there ought to be a way to do it from the IDE or from the command line.
But I noticed that in the zip binary you are told to download there is no changelog. So where is the changelog for the firmware documented? I would like to know what new or deprecated features are changes and what bugs there were that have been squashed.
Anyone know where to find the details on this?
Thanks.

What about running node server.js?
Woo hoo! Now why is that not in the faq? What is cool is it even tells you your device is not compatible and asks you to set the correct one.

Thank you so much. It was getting quite frustrating and I really think this sort of thing needs to be put into the documentation for the IDE.
Excellent now I can start with earnest tinking with my Pucks I have a few specific idea I need to test.
Thanks once again!!

Yeah.. I did that.. I even managed to connect to the PuckJS using bluetoothctl.

I have tried building the IDE from git and got a little further by just removing the requirement of winnus from the package.json file.
it 'installed' fine. But when I do npm start
npm start espruino-web-ide@0.65.11 start /home/user/devel/git/EspruinoWebIDE nw .

The winnus bit failed, but that's optional and for windows only
Hmm I was under the impression nodejs was cross platform. I mean what is winnus used for and is there a Linux equivalent to it I can add to the build options?
I will see if I can convince Chrome to play nice but seems non-trivial alas.
Thanks anyway, I put this question in Espruino because it was an IDE problem not an puck one per se. I can communicate to the puck from my phone, that is not so convienient though.
Thanks again.

Hi there,
So tried building EspruinoWebIDE from git and it fails because of a newer version of nodejs.
See attached file.
Also the Chrome app does not see my 2nd BLE adapter which is hci1. The adapter can see the PuckJS but the webide does not because it using hci0 be default.
hcitool -i hci1 lescan

Ok .. something definitely to do with the driver because this pops up in the logs:
I'll chat to the bluetooth subsystem guys see if I can get a definitive answer to what is going on.
