Rx1 Delay Setting in V3 Console

I’ve not seen anywhere to enter it for OTAA and TTI people have said that 5 seconds is the new standard - the network server will send the setting on join.

However what your device does is another matter so before migrating a whole host of them, you may want to read the documentation and actually test one. They may ignore the device JSON file or they may ignore the Network Server or they may get horribly confused.
