Trouble connecting

[datacute]

Windows & Chrome

Looking at the console output, the times I get continued spinning dots is always after selecting the device to pair to, and when WConfigurator receives either no response, or a battery status update, but no list of buttons:

{"filters":[{"services":["6e400001-b5a3-f393-e0a9-e50e24dcca9e"]}]}                                                                                  JSInterop.js:9 
BluetoothDevice {id: "d24NbMlbQWALgTpS0EIhQw==", name: "Espruino (T-Watch2020)", gatt: BluetoothRemoteGATTServer, ongattserverdisconnected: null}    JSInterop.js:96 
Characteristics listening

Sometimes that's all, other times I also receive:

[13,10,123,116,58,34,115,116,97,116,117,115,34,44,32,98,97,116,58,54]        JSInterop.js:106
[55,125,13,10]                                                               JSInterop.js:106

Which is {t:"status", bat:77} surrounded by CR LF, with no \x03

I have had it work too, when the console includes [3,123,34,97,112,112,34,58,34,105,114,34,44,34,114,34,58,34,108,105] ({"app":"ir","r":"li) etc

[anakod]

Thanks for feedback. Unfortunately in my case application works in most cases, I see issues relatively rarely. Can you please provide full connection logs from both Clock (UART output) and App (browser console)? I think it will be very helpful to resolve this issue.

Today I captured the serial log when a connection failed, and saw that the message was incomplete:

[I][blectl.cpp:210] onWrite(): msg: {"r":"list","t":"
...
[I][callback.cpp:196] callback_send(): call blectl cb (0x400d634c:0040:ir-remote setup)
[E][bluejsonrequest.h:23] BluetoothJsonRequest(): deserializeJson() failed: IncompleteInput

Retrying I received:

[I][blectl.cpp:210] onWrite(): msg: {"r":"list","t":"req","app":"ir"}
...
[I][callback.cpp:196] callback_send(): call blectl cb (0x400d634c:0040:ir-remote setup)
[I][IRController.cpp:143] IRController_bluetooth_event_cb(): RECEIVED cmd: list, msg: {"r":"list","t":"req","app":"ir"}

So I think the problem is on the watch, where I suspect the onWrite method is running concurrently with onConnect (which now deletes the message queue).

Actually - the log before the above gives more insight:

It is reporting that it is connected twice!?
Likewise the disconnect is getting reported twice.

[anakod]

Is it receiving onConnect() event twice in both cases, or only in case when part of message was lost?

it kinda worked the first few times i used it, but anymore i cant get anything but "An unhandled error has occurred. Reload" at the bottom of my screen

[anakod]

That's strange.

Bluetooth pairing unsuccessful

May be this is the issue reason? Is https://my-ttgo-watch.co.uk BT pairing working in your case?

[drunkscientist]

so i almost said that page worked fine (since it did yesterday) but i decided to try again to verify: it connects briefly before disconnecting again. the first time was too quick to do anything so i restarted my bt and tried again, it connected long enough for me to click on and get the step counter data before losing the connection again. grabbed logs from that page:

So looks like issue isn't in WConfigurator application directly?

[drunkscientist]

since i have an iphone, i cant use gagetbridge and afaik cant do much else with bt atm, so it could be faulty hardware for all i know. it definately DID work previously, and now doesnt. not on my desktop in linux or windows 10, nor my brothers laptop which is win10. i didnt touch any bt related code, nor do i use any in anything ive written. im assuming you havnt changed anything, which leaves something upstream, are the 2 pages built on common framework? is it worth trying with a different browser, say firefox instead of chrome?
