User reviews

Unreliable

I have only successfully used this once, every other time I have gone to update one of my Meshtastic nodes it fails and locks it out. You then have to plug the node into your computer to update it that way. This becomes a problem when you have a solar node on your roofโ€ฆ

Does work

Works ok for me.
A strong Bluetooth connection helps.

Buggy

Buggy app, seems to override other apps trying to connect to devices. Doesnโ€™t allow you to put devices into DFU mode which would be very helpful.

Canโ€™t find RAK

No worky

Totally useless with new update

This app used to scan for the Nordic DFU Service, which made it user friendly and very helpful. Now it shows all BLE devices and is completely useless.
