Error: Write failed on every attempt #77
Description
Whenever I try to write to a valid characteristic, the error "Write failed" always occurs. I'm trying to implement some code I found in the https://github.com/ib0b/RGB-PC repo into a NodeJS webserver project. The RGB-PC project worked perfectly fine on my machine, but implementing the same code with the webbluetooth library causes this error to happen.
this.server = await device.gatt.connect();
// await this.server.connect();
this.service = await this.server.getPrimaryService(
"00010203-0405-0607-0809-0a0b0c0d1910"
);
this.characteristic = await this.service.getCharacteristic(
"00010203-0405-0607-0809-0a0b0c0d2b11"
);
await this.characteristic.writeValue(commands.get("turnOn"));
