How to Fix Renogy BT-2 Bluetooth Not Connecting
Here are several methods to troubleshoot and resolve the connection issue, starting with the simplest and progressing to more advanced solutions.
Method 1: Basic Troubleshooting – Reset & Re-Pair
This is the first step to take and often resolves the issue quickly.
Diagnosing the Issue
Confirm the BT-2 module is powered on and the indicator light is blinking, signaling it’s in pairing mode. Ensure Bluetooth is enabled on your smartphone.
Fix Steps
- Restart your smartphone: A simple restart can resolve temporary software glitches.
- Reset the BT-2 Module: Locate the reset button on the BT-2 module (usually a small pinhole). Use a paperclip or similar tool to press and hold the reset button for 5-10 seconds. The indicator light should start blinking rapidly.
- Forget the Device: On your smartphone, go to Bluetooth settings and “forget” or “unpair” the Renogy BT-2 if it appears in the list of paired devices.
- Re-Pair: Open the Renogy BT app and follow the pairing instructions to connect the module again.
- Allow Permissions: Grant the Renogy BT app all necessary Bluetooth permissions when prompted.
Testing
Open the Renogy BT app. If the module connects successfully, you should see real-time data from your solar system.
Method 2: App Update & Reinstallation
An outdated or corrupted app can cause connectivity issues.
Diagnosing the Issue
Check the app store (Google Play Store or Apple App Store) for updates to the Renogy BT app.
Fix Steps
- Update the App: If an update is available, download and install it.
- Clear App Cache: In your phone’s settings, find the Renogy BT app and clear its cache.

- Re-Pair: After reinstalling, repeat the pairing process from Method 1.
Testing
Launch the updated/reinstalled app and attempt to connect to the BT-2 module.
Method 3: Firmware Update (If Available)
Outdated firmware on the BT-2 can cause compatibility issues.
Diagnosing the Issue
Check the Renogy BT app for a firmware update option. Not all BT-2 models support firmware updates via the app.
Fix Steps

Identify potential sources of Bluetooth interference nearby (Wi-Fi routers, other Bluetooth devices, microwaves).
Fix Steps
- Move Away from Interference: Temporarily move your smartphone and the BT-2 module away from potential interference sources.
- Turn Off Unnecessary Bluetooth Devices: Disable Bluetooth on devices you aren’t actively using.
- Change Wi-Fi Channel: If possible, change the Wi-Fi channel on your router to minimize interference.
Testing
Attempt to connect the BT-2 module after mitigating potential interference.
