I have a couple of devices that have the wrong RX_DELAY for V3. I tried updating the devices from the CLI using
ttn-lw-cli end-devices set --mac-settings.desired-rx1-delay RX_DELAY_5
But if the device only has the rx windows open for 1 second it is never going to recieve that update. Like a catch-22.
So I was thinking to set the value as an application-setting on the application with
ttn-lw-cli applications activation-settings set --mac-settings.desired-rx1-delay RX_DELAY_5
But that gives an error msg and I cannot find out what the correct syntax is. I am sure it is documented somewhere but I cannot find it.
BTW These are OTAA devices… in case that matters.
Any help is greatly appreciated.
