Locker not found
One of the most common issues is trying to open a lock through a port that is not connected to a lock. Here’s an image of one of our boards with the ports labeled 1-20
If you are trying to open lock 4 but you only have ports 1-3 connected then you will get the error: 502 Locker not found.
Locker status changing, but lock not firing
Scenario: When opening the locker with my app, the lock does not open but the status of the locker in Harbor Console changes to “rented” or “occupied”
Hardware causes
Lock/Board connection wire loose
this lock will not be able to communicate with the tower properly.
Lock wire correctly plugged in example:
Software causes
How to fix it:
There’s many reasons why this error happens, here are some of the most common issues and their solutions:
Your app does not have sufficient bluetooth permissions. Make sure you’ve followed the directions of how to request bluetooth permissions of your platform.
If you believe bluetooth is working properly: try resetting the events from Harbor Console.
Your app is creating the drop off token but not sending it to the locker, so the locker is staying in “Rented” state.
Fix: Make sure you are syncing with the tower before creating the drop off token. Discovering towers
Cannot connect to tower
1. The most general one is: Check your credentials Double check your client and your client_secret and make sure they are right. Check with us at harbor too to make sure there wasn’t an issue copying it in transit.
2. If your credentials are fine, Check your environment. If you are asking production to connect to a sandbox board it will not work. You can find more information about environments here: Get Access Tokens.
Make sure you are close enough to the tower. You should not be more than a 10ft from the tower otherwise bluetooth can disconnect.
Factory reset without using the app
The board has a factory reset button that can be accessed through a small pinhole on the side of the plastic case. Use a small item (like a toothpick) to press this button and hold it for 10 seconds to get the board to factory reset.
