Nodes don't always connect to app

[RJKcustoms]

Hello,

Only been using meshtastic for a couple of weeks.
I seem to be having a problem where my devices don't always connect and when they do connect they disconnect themselves intermittently.
I'm using Heltec V3 boards and the android app. 1 is a solar node on the roof of my house and the other is a handheld device.

When I first started noticing this if I turned Bluetooth off and back on they would connect but now nothing I do seems to get them to connect reliably.

Thanks for any help
Ryan

I have a similar issue with my heltec v3 where the app seems to get stuck while connecting to the node and I can see for example it's sitting at 'module loading 12/13' and then it's stuck there. If I disconnect and connect again it works but I've noticed that sometimes I miss messages because they see seem to be skipped with these failures.
I have the seedstudio sensecap tracker t1000e and I never have a problem with this one.
