Hi,

I think one of my blinds is very low on power, and although the initial connection works, it doesn't actually respond. This app gets stuck waiting for a response that never arrives:

If I remove the trouble device (i.e. 02:18:89:A0:F8:4A) from the startup command, so that only the other blind is specified, it works no problems!

Hmm I was wrong, even with just the one device specified, although it doesn't immediately get stuck in a loop, as soon as I issue a command it does:

The only other info I can share is I'm running on a Pi3, with nodejs 12.20.0 (nodejs 14 wouldn't even npm install this project). I had the following error during installation:

It seems that the data reading sequence for battery etc does not complete and somewhere hangs (unless your log snipped was not complete)
The log should end with 'data reading successful':

You can try to update the Bluez drivers on raspbian. Command 'bluetoothctl -v' shows you your current version.
Tutorial: https://github.com/zewelor/bt-mqtt-gateway/wiki/Upgrade-Bluez-on-Raspbian
Check for latest version (seems to be bluez-5.55.tar.gz at this moment)

Hey thanks @binsentsu. I was on 5.50 already but upgraded to 5.55. No difference. It stops doing anything after Notification identifier: 00 +1ms unless I issue a command, and then it goes into the stuck loop.

For what it's worth, I was previously using this project, which connects and issues commands, and gets the status fine (but lacks HA/mqtt):

I've also used

So looking at where mine hangs, am I understanding the code right, it looks like mine fails reading the light data? My "notification identifier" seem to be different, yours is aa, mine is 00

Your log:

I think the issue is that these are defined in the code:

const batteryNotificationIdentifier = "a2";
const positionNotificationIdentifier = "a7";
const lightNotificationIdentifier = "aa";

but mine is returning 00. Looking at the code, I think there is no else if statement to handle when the NotificationIdentifier is not one of those 3 above, so the app just hangs. I'm not really a developer so just a guess :)

I tried adding:

else {
self.writeLog('Notification identifier unknown');
self.writeLog('Skipping');
}

to the discoveryResult function, which it outputs but it still gets stuck. I guess as you said, something odd is happening in the readData() function, since "delaying data read" is what it eventually outputs.

It's not clear to me where this function (readData) is actually called. I suppose what is supposed to happen is discoveryResult - characteristic.on('data', function (data, isNotification) {} loops until battery, light and position are found. I don't understand the code enough, as I cannot see readData() being called anywhere in this loop :( I added some logging and confirmed this is where it gets stuck:

am43:025a5eb7aab5 entering readData() +0ms
am43:025a5eb7aab5 Connection busy for other device, delaying data read... +0ms

Any chance of adding some error handling here or a timeout? Many thanks!

Same issue here. Not sure I can provide any additional information. Running in RPI4

did you manage to resolve this? I am having the exact same issue as you described in your OP. @binsentsu can you please look into this? thanks

@binsentsu
I'm running into this issue as well. I'm running this on a RPi3 and get the same situation. First command runs fine, but after a short while, connection is busy for other device, delaying data read.
Has this been solved after 2 years?
