The // remove the reset from the rf device code block results in the radio never being able to enter lp, (SPWD strobe fails)

Hi @tony-gutierrez, thanks for submitting issues. May I ask what hardware platform are you using? This project is based on an evaluation kit more than two years old. If you don't mind to test it and create a PR, I would really appreciate it.

Msp430f5529 with the cc1120-90 boosterpack. I have been fighting hard to get decent battery life for a project. Took over code that was obviously based on yours. I'm very curious if the next block (cc1190 idle config) will help me but can't test until tomorrow. If you have any low power tips I'm all ears.

Would love to help. But at this point, you probably have done way more research in achieving low power consumption than me. It seem issuing SPWD over spi after setting SIDLE should do the trick. Seems idle state is required before power down.

Have you tried power down 1190 too? http://www.ti.com/lit/an/swra492/swra492.pdf

1190

I won't get access hardware till early next week. Will see what I can do.
