what problem are you having? I have one meshtastic device attached to a high gain antenna on the top of my house. with another one that I use with my phone. I have also put one that is using wifi instead of bluetooth so that I can bridge MQTT. I dont have any problems. but I only connect my phone to one of the mehtastic devices. the others are for bridging or the one with high gain antenna is for getting distance to a buddy of mine who has a device about 4 miles away.
