Dear sir, how to get the txpower level at the transmitted packet? #814

Describe your question or issue

When set LMIC_DEBUG_LEVEL we can get the frequency information, but how to get the power? Because I am testing the mac command about ADR, I need to know that the power has changed and has changed to the correct value.

Capture it at EV_TXSTART time. Look at how the compliance sketch does this.

By the way: please do not use LMIC_DEBUG_LEVEL except to debug crashes. It ruins timing, and therefore the LMIC will not behave correctly. I have not wanted to remove it, but it's not useful except for crash tracing. It is especially useless for looking at ADR performance and anything else that requires downlinks to work.

I am not exaggerating.

You must never print while the LMIC is doing critical work, and if you're in the LMIC, you're doing critical work. You must log, and then print after the LMIC finishes up. The compliance sketch is currently the best example.

Thanks, --Terry
