Hi,

I write the bytes to turn on the LED of the sensor tag by using I/O services.

I am trying to write 1 byte and its working but it turned on the buzzer instead of the LED.

Here is my code :

var valueToWrite = 1

let data = Data(bytes: &valueToWrite, count: 1)

handler?.writeValue(data, to: ioService)

i am using swift as a language.

Try to refer to processors.wiki.ti.com/.../CC2650_SensorTag_User's_Guide

Hello,
Sounds like you are either writing to wrong IO or you have modified HW platform. The users guide YK Chen is referring to should help.

Hey Joakim,

i am writing at TI_SENSORTAG_IO_CONFIG "F000AA66-0451-4000-B000-000000000000"

and my code is
- (void)writeTurnOnRedLEDForCharacterStics:(CBCharacteristic *)characterstics {

uint8_t valueRedLedOn = 0x01;

NSData *data = [NSData dataWithBytes:&valueRedLedOn length:sizeof(valueRedLedOn)];

[self writeValue:data toCharacteristic:characterstics];;
}

and now it turned on everything (red,green and buzzer), not sure what's wrong with the sensor tag, i bought new one just to test. but still it's not working.

Can you please send me some example or a way to debug it.

Hi,

As YiKai points out you should read the documentation for the IO Service at processors.wiki.ti.com/.../CC2650_SensorTag_User's_Guide

You should first make sure that the value in the DATA characteristic is sensible. Write 0x01 to it to set bit 0 for the RED led. Then write 0x01 to the CONFIGURATION characteristic to put the IO Service in remote control mode.

Best regards,
Aslak
