Hi,

You can create multiple profile. Use different to send differnet data. Refer this link. Custom profile.

Or send the different data sequentially using one service. The program uses timer to send the data. So first time ,you send the temperature. Second time, you send the other data.

Or you can combine these data. For example, you can define a 32 bit variable. The high 16 bit uses for temperature, and the low 16 bit use for humidity. Then send this 32 bit variable. You will get two different data.

Have a great day,
