Receice MAC command

[daeynasvistas]

i do receive MAC command from NS server

do the lib really apply the "power to 2" change on the node?
power to 2 are the same as LMIC.setAntennaPowerAdjustment(-14); ?

ADR REQ Change dr to 5, power to 2

im very close to the gateway

[daeynasvistas]

it seems that its try to change sx1276 power.
i will try to see the gateway log to compare the dB in there

Yes the transmitting power is reduce when the network send this type of MAC command.

For example for EU868 the transmission power is -2*the value send by the server (value define in lorawan regional settings).

So the lib ask to sx1276 to transmit with power :
14 - 2*(the value in ADR request) + AntennaPowerAdjustment .

But the sx1267 power can be set from +2 to +17, so the minimum TX power asked is always +2 (most board do use PA pin see PA_BOOST_PIN)
