Hello,   I've been tasked with doing some wifi surveying at local parks using the Meraki MR74.   I just have a few questions and i'm hoping one of you can help me out.   The goal is to go from Root Ap to Mesh AP to the next Mesh AP.  Is this a possibility with the MR74 if I use 3 of them?    Is there a testing mode that the antenna can enter that emits a signal that I can use with a heatmapping software?   Thank you ...
