[ Lorawan_End_Node application] Transmit at lower power

Hi all,

I want to do some tests to simulate "low coverage" conditions

How could I quickly make the equipment transmit at less power?

For example in the EU868 region limit to 10dBm instead of the 14dBm that is allowed, or in US915 to 20dBmn instead of the 22dBm

Best Regards,

Sergio

Hello,

You can modify the Tx power for each region in the header file of this region, for example RegionEU868.h.

You can define the minimum and the maximum Tx power that can be used by the node.

Be aware, the index 0 stand for the maximum Tx power.

Best Regards

Louis

Hi,

So, wouldn't it be better if what I want is to change the maximum power in dBm, directly modify the EIRP of the region?

Hi,

Yes this is also an option
