We have had several requests from customer that are wishing to put in an autopilot cnPilot solution as they are not wishing to manage the solution post installation. They have requested the feature to be able to mesh two E-Series access points using the autopilot method. This is not currently supported. In 2017, there was a reply to a post on the cambium forum, suggesting that this would be included in a future firmware, however there is no indication from support to when this would be the case.
mesh on autopilot is not on the immediate roadmap (not next 3 months) but we are going to prioritize this in a software release later in the year. Will update again once we have firmer timelines on this.
