Meshtastic Amplifier?

I wondered if there was such a thing. Here is a video demonstration of a 10dB bi-directional amp for Lora devices.



This channel also has some antenna builds for Lora devices.


Here is the link to the amp he talks about:

Oh, wow, I am 300 feet away from a cell tower and I did not even think if this Thanks!

Did your Bluetooth connection to phone app stop working?

I am on version 2.7.8 (29319501) of the Android app, which was just installed about a week ago. Since then I have had to reboot any Meshtastic node to connect via Bluetooth. I can pair with the node ok, but the app will not connect via BLE unless I reboot it. Kind of tough when the node is 40 feet up in a tree.


Anyone else having this problem?

I updated on Android. BLE connection issues persist, but it prompted me to try the web client. I can connect to my remote outside node over BLE using the Web Client. I am more than a little chagrined that I never used the web client before. BTW, I have a node inside in the attic to which I have attached the bi-directional amp and the notch filter. I tried to setup a wifi connection for that node, but there apparently is a bug in the Android app that will not expose the network setup page. However, the web client works fine and I now have a node connected to wifi.


MeshCore?

Here is a good video comparing MeshCore to Meshtastic.
