[CC1310 LaunchPad Low Power]

check this topic: 

 

These functions are not ready for cc13xx yet, sleep() in particular is already implemented automatically inside delay()... if nothing is done by the CPU, the idle function runs (which is a TI RTOS thing) that negotiates the lowest power mode available and enters it.

[Bootloader on CC1310]

1. Yes

2. JTAG, you can verify this by removing the JTAG jumpers and keeping the serial ones (upload will fail, which proves it uses JTAG)

3. eveything is possible, but I'm not aware how to do this 

[Energia1.8/1.6 don't support sleep()]

what's the solution?
