Extend range of ESP module

By MrMU
- Thu Jul 13, 2017 11:31 am #68215 I've got several modules that I tested to serve as an AP.

They are all short on output power (or better, the range I can talk to them is a bit too short).
On one module I've hooked up a ducky antenna, but this doesn't seem to extend the range compared with a PCB antenna.

Is there a way to extend the range for these modules?
In the AT-commands datasheet I've found AT+RFPOWER to set the output power to maximum.
Is there a way I can set this and keep the settings?

Or is there a command in the Arduino IDE that I can use to set the output power to max?

It's a nice comparison between several boards and set-ups (and it's always fun to listen to his Swiss accent). ;)
