pix1289 has just created a new issue for https://github.com/WebBluetoothCG/web-bluetooth:
== NotSupportedError: GATT Error unknown when writing to device using web bluetooth API ==
I am using Angular version 7 on windows 10 and @types/web-bluetooth package.
My App was working as expected. The data was being written to the device using writeValueWithoutResponse/writeValueWithResponse methods of web bluetooth API. Now it is not working and throwing an error. I have attached chrome logs as well as console logs. Please help.
PFB my code:
navigator.bluetooth
.requestDevice({
filters: [{ name: this.deviceName }],
optionalServices: [this.GATT_SERVICE], // required if filtering is by name
})
.then((device) => {
// Step 2: Connect to it
console.log("device:", device);
return device.gatt.connect();
})
.then((server) => {
// Step 3: Get the Service
console.log("server: ", server);
return server.getPrimaryService(this.GATT_SERVICE);
})
.then((service) => {
// Step 4: get the Characteristic
console.log("service: ", service);
return service.getCharacteristic(this.GATT_CHARACTERISTIC);
// return service.getCharacteristics();
})
.then((characteristic) => {
characteristic.writeValueWithResponse(this.data);
}).catch((err) => console.log(err))
