subscribe multiple

[screengarden]

hi,

i'm new to bluetoothle. how can i subscribe to multiple characteristics?

if i write the following code, my app is doing nothing. if i write just one block (one subscription) everthing is fine.

please help me. ` bluetoothle.subscribe(function (result) { if (result.value) { var ergebniss = app.convertBytearray2dec(result.value); document.querySelector('#TXT_AKKU_LOW').value = ergebniss; } }, function (e) { console.log(e); console.log("subscribe fehler"); }, { "address": app.deviceAddress, "service": app.werte.OWNSERVICE, "characteristic": app.werte.AKKU_LOW });

bluetoothle.subscribe(function (result) { if (result.value) { var ergebniss = app.convertBytearray2dec(result.value); document.querySelector('#TXT_ZUGKRFAT_LOW').value = ergebniss; } }, function (e) { console.log(e); console.log("subscribe fehler"); }, { "address": app.deviceAddress, "service": app.werte.OWNSERVICE, "characteristic": app.werte.ZUGKRFAT_LOW });

bluetoothle.subscribe(function (result) {
    if (result.value) {
        var ergebniss = app.convertBytearray2dec(result.value);
        document.querySelector('#TXT_ZUGKRFAT_HIGH').value = ergebniss;
    }
}, function (e) {
    console.log(e);
    console.log("subscribe fehler");
}, {
    "address": app.deviceAddress,
    "service": app.werte.OWNSERVICE,
    "characteristic": app.werte.ZUGKRFAT_HIGH
});

Yes, it should be possible. I've used it once but thats some time ago. Though I used a subscriptionHandler function as callback for each subscription. Maybe try something like this?

bluetoothle.subscribe(subscribeHandler, errorHandler, { "address": app.deviceAddress, "service": app.werte.OWNSERVICE, "characteristic": app.werte.ZUGKRFAT_HIGH });

function subscribeHandler(result) {
if (result.service === app.werte.OWNSERVICE && result.characteristic === app.werte.ZUGKRFAT_HIGH) { // do stuff }

if (result.service === app.werte.OWNSERVICE && result.characteristic === app.werte.AKKU_LOW) { // do stuff } }

That looks perfectly fine. Do you see any runtime errors? Maybe add a console.log to the success handler to double check.
