Our take on the OTA Programmer

The Hobbywing OTA Programmer is a tiny Bluetooth module that links a Hobbywing ESC to a phone or tablet. It lets you program settings, flash firmware updates and watch live data through the Hobbywing HW Link app instead of a programming card or PC cable. At about 10 g and 30 mm long, it disappears in a pit box. It suits racers and bashers running compatible Hobbywing ESCs who want quick trackside changes. The catch is narrow compatibility: it only works with Hobbywing ESCs and the HW Link app, and its 3 m open-field range means keeping the phone close.

About the OTA Programmer

The OTA Programmer is a pocket-sized module that uses Bluetooth to transfer data between an ESC and a smart device, such as an Android phone or tablet. It lets you program and upgrade the ESC wirelessly and monitor the data being transferred.

It supports HOBBYWING over-the-air firmware updates and gives access to HW Support, including the user manual and profile manager. A fail-safe feature disables throttle control while OTA programming is enabled.

It works with some XERUN and EZRUN series car ESCs, some PLATINUM series aircraft ESCs and some SEAKING series boat ESCs. Check the ESC manual to confirm that a specific ESC works with the OTA Programmer.

Questions and answers

Which ESCs does the OTA Programmer work with?
It is made for compatible Hobbywing ESCs that support OTA programming. Check your ESC model in the HW Link app or Hobbywing's compatibility list before buying.
Do I need a phone to use it?
Yes. It pairs over Bluetooth 4.0 or newer with an Android or iOS device running the Hobbywing HW Link app, which handles programming, firmware updates and data monitoring.
Can I drive while it is connected?
A fail-safe disables throttle control while OTA programming is enabled, so you program with the vehicle stationary and then disconnect.
How far away can my phone be?
The rated range is 0 to 3 m in open field. Keep the phone close to the vehicle; walls and other gear shorten the link.

The package contains the OTA Programmer module itself. The HW Link app is a free download, and you supply the phone or tablet.
Does it replace a programming card?
For compatible Hobbywing ESCs, yes: it covers the same settings plus firmware updates and live data. For other brands or older ESCs, you still need their own programmer.
