Hi @ajudge ,

The Tx-power on the EKH01 is shown as 20 dbm

We would like to increase the power to it’s maximum supported value (27dbm)

Can you please provide us the command to increase the Tx power.

Thanks,
Arti

The module used in the ekh01 is not capable of transmitting at 27dBm.

Hi @ajudge ,

Does it mean that EKH01 can have TX power only upto 20dbm?

Also, Do we have any command, to get or set the TX power from command line?

Thanks,
Arti

The screenshot you showed is the output from OpenWrt’s iwinfo command; you can use this on the command line.

If you want the output in JSON for easier processing, you can call iwinfo via ubus (ubus call iwinfo ...).

If you want to modify the txpower, you can do this via the wireless config page in LuCI, or via UCI directly:

uci set wireless.radio0.txpower='10'
uci commit wireless
reload_config

Hello, I tested the command line you suggest but it does not work, I want to modify the Tx_power = '13’dBm, but it is still 20dBm.
Thanks

Sorry, my apologies, this is the generic way to set txpower on OpenWrt but the Morse bring-up doesn’t support changing the txpower via this mechanism at the moment.

You can set the txpower manually via iw after you’ve brought up the interface, though. To set it to 10dBm:

iw wlan0 set txpower fixed 1000
