What is Firmware and how do I install it?

Firmware is an update to the product and will require the digital controller to be connected to Wi-Fi. It is recommended that firmware updates be completed on 2.4GHz Wi-Fi connections (NOT 5GHz). It is not recommended to update over hotspot connections. When updates are available you will get a prompt to update your grill's firmware when opening the app.

How to Update

Tips For Wi-Fi

Use a 2.4ghz Wi-Fi network (not 5Ghz) with a strong signal to set up Wi-Fi on the grill

Temporary hot spots are not recommended

Changes to the modem/router settings may cause the grill to lose Wi-Fi connection and setup will have to be repeated

Digital Charcoal App Overview

For an overview of how to set up the app and connect to your device see the Digital Charcoal App Overview

In case you experience problems during the initial set up or subsequent connectivity, follow the steps below to set up the grill once more:

1. Unplug the grill.
2. If you have the grill added in the App, remove it by tapping the "X" button.
3. Sign out of your Masterbuilt account using the profile screen.
4. Delete the App.
5. Restart your phone.
6. Reinstall the App.
7. Sign in to your Masterbuilt account.
8. Plug in the grill.
9. Follow steps to add the grill.

If Wi-Fi is not present, can the controller be updated through Bluetooth?

No, the controller can only be updated through a Wi-Fi connection.

The connection icon is blinking on the grill's controller

When the grill lid is opened, the ability to control the grill is disabled for mobile devices and placed in a “monitor only” mode until the lid has been closed and the “connect” button is pushed to re-enable full functionality for a mobile device. Every time the lid is opened, the user will need to push the connect button in order to gain mobile device control as a safety precaution.

Do I need to update the controller before I use the grill?

We do recommend updating the controller before using the grill to ensure it is running on the latest update, but it is not required before using the grill.

Tips For All Other Smokers

Connect/Pair Using the Masterbuilt Classic App Only

DO NOT use the Bluetooth feature of your mobile device settings to search and connect to the smoker. To pair your device use the Masterbuilt Classic application only. If you have already paired simply unpair/forget device setting in your mobile device and repair using the Masterbuilt Classic application.

Always use the latest version of the Masterbuilt Classic App and Operating System

Update to the most recent version of the Masterbuilt Classic Application and/or phone Operating System prior to pairing.

Confirm Bluetooth is ON by checking the mobile device settings

Ensure Bluetooth is turned on and ready to connect.

Ensure Airplane/Power Saving modes are turned off

Power saving and airplane modes can turn off Bluetooth functionality.

Make sure your mobile device has a sufficient charge

A weak battery or low charge may not have the power needed for the Bluetooth signal to reach the smoker.

Move your device away from potential sources of interference like wireless routers, microwaves, poorly shielded electronic cables, and garage door openers

Delete any saved settings on your phone by clearing app cache or reinstalling the app

Make sure there are no other devices connected to the smoker

Only one device can be connected to the smoker at a time.

Turn your device off for 20-30 seconds then turn on the mobile device again

Unplug the smoker for 20-30 seconds then plug it back in

Once you have followed the steps above try to pair your device to your smoker. If you experience problems pairing your device to the smoker after following the steps above, please contact our customer service department for assistance.
