UBX Contest
Announcement: Winner of the UBX Developer Contest!¶
We are excited to announce the winner of the UBX Developer Contest, where developers were challenged to implement a fully working radio side GPS uBlox UBX protocol in EdgeTX's main GitHub repository. This required parsing essential fields like latitude, longitude, altitude, and more from the UBX protocol, similar to the current NMEA parsing in EdgeTX.
After careful evaluation and consideration, we are proud to declare David Pham-Van as the winner! As a token of appreciation for his outstanding contribution, David will receive a RadioMaster Boxer MAX radio (per his request), generously sponsored by RadioMaster. This state-of-the-art radio will be shipped worldwide free of charge directly from the RadioMaster factory to David.
We extend our heartfelt congratulations to David Pham-Van for this well-deserved win. Your contributions continue to enrich the EdgeTX community and propel its growth forward.
Contest Details¶
Task:
Be the first developer to make a pull-request (PR) against EdgeTX main GitHub repository with fully working radio side GPS uBlox UBX protocol implementation, including a link to a short video demonstrating the functionality in the GitHub pull-request post.
The solution should minimally parse from UBX all in EdgeTX currently supported fields that are parsed from NMEA, such as:
- latitude
- longitude
- altitude
- HDOP
- number of satellites
- lock status
- speed
- heading
- date
- time

On color radios, following widget should continue to work: https://github.com/EdgeTX/edgetx-sdcard/tree/master/sdcard/c480x272/WIDGETS/TxGPStest and RTC clock sync should also continue to work with UBX GPS communication protocol.
