Part Number: CC1310
Other Parts Discussed in Thread: TMP116, SIMPLICITI

Tool/software: TI-RTOS

Hello,

I have a custom PCB interfaced with a TMP116 (i2c) sensor, two tasks have been created for this purpose, one for reading the temperature and the other for RF communication, the RF communication is working well and I have could even read temperature.
I left step by step, when i add the part i2c tmp 116 the microcontroller consumes the current 129 uA, how to act in this situation?
knowing that I aim to reach a current of 4 uA.

Hello,
To clarify the situation here is the task concerning the temperature part, if you have time to see this code, please?
