Hi, I am working on a channel sounding trilateration system using an initiator and three reflectors. When I was testing with six reflectors I couldn't help but notice the interference that was taking place when they were placed close to each other. Although now when I placed them further apart and reduced the amount of reflectors they work a lot better, I still want to make sure there is minimal interference. Currently all the reflectors are advertising but only one is performing the channel sounding procedure at a time, this means that the other devices that are advertising are interfering with the active one. In order to combat interference I thought I could make a wake up system through GATT messages. When the initiator is done with a reflector, it disconnects from that and then sends a GATT message to the next one to tell that specific one to start advertising so they can make a connection. This way only way device is advertising at a time. But when the reflectors are listening for GATT messages does that also introduce interference? Is this solution sound? Or are there side effects other than being more complex that I don't know about? Also, does anyone have any resources that can assist me in building this system? I tried searching up GATT messaging but there is barely anything close to what I need. Thank you!
