EP Carry Firmware Update Procedures

Follow this EP Carry firmware update procedure to download the correct file and install it safely on your motor.

General Process

• Download nRF Device Firmware Update from the App Store.
• Download the EP Carry Firmware from this site.
• Save the firmware file to a folder on your phone.
• Run DFU to update the EP Carry firmware.

Process IOS

Step 1

Download the app nRF Device Firmware Update (DFU) from the App Store onto your phone.

Step 2

Open the email from PropEle. The following screen will appear. Click the icon with the downward arrow.

Step 3

Click the Share icon, and then select “Save to Files.”

Step 4

Select a location for the file. Tap “Save,” and then tap the back arrow.

Step 5

Open the DFU app on your phone. Then tap “Select.”

Step 6

Select the correct file. In this example, 270W EPC V1 is selected from among the other versions on this phone.

Step 7

Enable the motor’s Bluetooth radio. Set your phone aside while completing these steps. Every EP Carry has a Bluetooth radio that can be enabled for programming.

Important: Make sure the safety key is removed from the throttle before connecting the battery to the motor.

• Put the knob in the Off position, insert the magnetic key, and remove it.
• Move the knob to Full Throttle, insert the magnetic key, and remove it.
• Put the knob in Full Reverse, insert the magnetic key, and remove it.

Troubleshooting: If you cannot see PropEl in the Bluetooth device list, repeat Step 7. If Bluetooth still does not appear, the knob magnets that provide the position signal may be degrading. A replacement knob is available from EP Carry. For help, call (425) 502-5232 or email info@electricpaddle.com.

Step 8

Select PropEl from Devices.

Step 9

Tap “Upload.” The upload progress will be displayed.

Step 10

Finished. Your motor can now reach 22% higher power levels when using a 24 V or 36 V battery, and thermal protection has been added.

Prior firmware versions did not allow the use of 12 V batteries because they cannot provide enough voltage for full-power operation. This version allows 12 V operation for emergencies, but at a much-reduced power level. To access full power from a 12 V battery, EP Carry sells a 12 V boost kit.

Procedure

Step 1

From Google Play, install the app nRF Toolbox for BLE.

Step 2

From the email containing the firmware ZIP file, save the file to your local files. To do this, tap the ZIP file and select “Save.”

Step 3

Open the nRF Toolbox app.

Step 4

Tap “DFU.”

Step 5

Tap “Select File,” select “Distribution packet (ZIP),” and tap “OK.”

Step 6

Select the file that you saved from the email.

Step 7

For Select Scope, select “All,” and tap “OK.”

Step 8

The file should now be visible.

Step 9

The next step is to select the device (your motor’s controller). First, enable the motor’s Bluetooth radio. When the battery is disconnected, the motor will revert to disabled Bluetooth, so leave it connected until the update is complete.

• Connect the motor to your battery.
• Move the throttle to the Off position, insert the key, and remove it.
• Move the throttle to Full Forward, insert the key, and remove it.
• Move the throttle to Full Reverse, insert the key, and remove it.

Step 10

Tap “Select Device.”

Step 11

If this is the first time nRF Toolbox has been used, you may receive a permission dialog.

Step 12

Select the PropEl device.

Step 13

Tap “Upload.”

Step 14

A progress bar will appear during the upload. When programming is complete, the screen will confirm that it is done.
