GP-PWM-30-UL: Bluetooth Connection Issues

Diagnosing Connection Issues

  1. Make sure Bluetooth is turned on. You should see the little Bluetooth symbol at the top of your phone’s screen. If you don’t, go into the settings to enable it.
  2. Determine which pairing process your device employs. In the case of our solar controller hold down the A and B button at the same time
  3. Turn on "discoverable" mode.  First, go into your phone’s settings and tap on Bluetooth; doing so makes the phone visible to the controller. 
  4. Make sure the two devices are in close enough proximity to one another
  5. Power the devices off and back on. A soft reset can sometimes resolve an issue.
    • With phones, an easy way to do this is by going into and out of airplane mode.  
  6. Remove old Bluetooth connections. Say that faithful Bluetooth speaker usually connects to your partner's smartphone instead of yours. If you're having trouble pairing your phone with the speaker, it could be because the speaker is trying to connect to the old device. Some older devices are very simple. They just try to connect with the last thing they paired with. If a Bluetooth device was previously paired with something else, turn off that other gadget. And if you are no longer planning on using that other device, unpair it from your Bluetooth device to prevent future issues. In iOS settings, you can remove a device by tapping on its name and then Forget this Device. In Android settings, tap on a device’s name, then Unpair. After removing a device, start at step 1 on this list.

    You can also reset Bluetooth on devices that can pair to more than one device. This clears all pairings from the device so you can start fresh. Search "reset" device name to instructions from the manufacturer.

  7. Charge up both devices you're trying to pair. If the battery voltage drops below 11 VDC it may affect Bluetooth operation
  8. Delete a device from a phone and rediscover it. If your phone sees a device but isn’t receiving data from it, sometimes it helps to start from scratch. In iOS settings, you can remove a device by tapping on its name and then Forget this Device. In Android settings, tap on a device’s name, then Unpair. After removing a device, start at step 1 on this list.
  9. Get away from the Wi-Fi router. Another potential obstacle to successful pairing is interference from devices that use the same spectrum, such as your Wi-Fi router. Wi-Fi has been designed to cope with this, but it might not be a good idea to have your devices directly on top of the router.
  10. Move away from a USB 3.0 port. Interference from USB 3.0 is also possible. Newer laptops, for example, often have the higher-speed USB 3.0 port, so if the connection isn't happening, try pairing your Bluetooth gadgets away from the computer.
  11. Update the hardware’s firmware. IOS and operating system upgrades can sometime cause connectivity issues that are repaired on later versions of the OS.
  12. Clear the Bluetooth cache (Android only). Sometimes apps will interfere with Bluetooth operation and clearing the cache can solve the problem. Go Settings > System > Advanced> Reset Options > Reset Wi-fi, mobile & Bluetooth

 

To hard reset the controller, power from the battery and solar panel will have to be removed from the solar controller, as seen in this video:
