Set TX Power in LoRaWAN Mode

[timrid]

Hello everyone.
How is it possible to set the TX Power in LoRaWAN mode? If this is not possible, how can I read out the current TX power?

Hello everyone.

According to the documentation tx power can be set in raw LoRa radio mode, but not in LoRaWAN and no method to read current tx setting. When ADR is enabled, Network Server is controlling both Data Rate and Tx Power of the device but you can't get actual setting, nor DR nor Tx Power.

It is pity.

If this function is not available, how do I know with which TX Power I send by default? (If the ADR is deactivated)
Is the maximum transmission power of 14 dBm then always used?

@timrid
Yes, that is the default set in lib/lora/mac/LoRaMac-definitions.h for region EU 868Mhz, for the US/915Mhz it's 20 dBm

Sorry for replying to a very old post, but I was wondering if this has changed after 9 months or we still are unable to set the transmission power when operating in LORAWAN mode.

PS: In certain situations ADR is disabled and still, we cannot set that important feature

Hi @rubenmsandoval, there has been no change

@dan Well, don't understand why it is like that.
Due to a research project I have had to "hack" the libraries to allow changing the transmission power. Should anyone need it, send me a PM (I have just programmed a "dirty" workaround so not even daring to push a change to github or something like that!)
