I have confirmed with the engineering team and for cnPilot R200P or R201P devices which are already being used, the devices needs to be reset in order to get the cnMaestro url from DHCP server as by default they will have static url of cloud.cambiumnetworks.com or other cnMaestro urls configured. We will update the user guide accordingly.
For all other device types , please remove the static cnMaestro url configured if any from the devices so that the devices will automatically get the option 43 and on board to cnMaestro server.
Regarding the configuration of DHCP server in Microtik Router to allow multiple option 60 so that all your devices can on board to cnMaestro server . please follow the following KB Article and if you need any further help please let me know.
What do you mean 'reset'? Does that mean rebooted, or factory defaulted?
I've looked at the DHCP Options section (p30) in the 1.6.1 Maestro user's guide but I'm not sure yet if a DHCP option will overwrite the default url. Will this happen after a new DHCP lease, a reboot, or a factory defaulting?
