### 3/5 — Cannot upgrade firmware for bluenexus

*2024-06-17*

I’m on an iPhone and have been trying for over an hour to upgrade the robots firmware and it keeps failing. My connection is more than fine, has to be an issue with the app. Please fix this.

### 3/5 — Update: Stuck on step 3 of connection

*2023-11-21*

Update: I was able to connect on an Android device and now I can see the Robot on my iPhone. Will add additional updates if relevant.

I am connected to the robot wifi but cannot move forward.
