ADR TXPower doesn't change #50

Closed DylanGWork closed 11 months ago

DylanGWork commented 2 years ago

I've started testing ADR and I can see the MAC commands from the network server changing the TXPower, however the TXPower appears to stay at the maximum setting.

Am I able to print out MAC downlinks to see what's coming in?

Cheers, Dylan

Hi Dylan

I propose you experiment with the following macros:

LMIC_ENABLE_event_logging=1

LMIC_DEBUG_LEVEL=1

LMIC_DEBUG_LEVEL=2

and then watch for scan_mac_cmds_link_adr and applyAdrRequests.

It is a functionality that this library fully relies on the LMIC library.

This output is from Debug level 2:

I'll have a look through the LMIC library as well to see if anybody has experienced this from the main github.

Just a sec, redoing with LMIC_ENABLE_event_logging turned on, will edit this post

I don't appear to be able to build with LMIC_ENABLE_event_logging=1:

manuelbl commented 2 years ago

@DylanGWork I'm surprised you are getting these errors. It successfully builds when I add the following lines to the top most CMakeLists.txt:

add_definitions(
    -DLMIC_ENABLE_event_logging=1
    -DLMIC_DEBUG_LEVEL=2
)

Additionally, I don't fully understand the ADR TX power management. The way I read the code, the transmitted TX power is now used as the upper limit. But I might be wrong...
