September 26th, 2021 – v1.0.0.24

ADDED: Improved workflow for Arduino-only updates on the Echo. Simply select the Arduino code only and leave the display field blank, and press Update.

September 2rrd, 2021 – v1.0.0.23 Initial Release

Nextion NX4827K043 “Enhanced” Display Support #

October 23rd, 2021 – NX4827K043 Display Support

ADDED: Display firmware that will work with the Nextion “Enhanced” displays. These displays perform similar to the Basic ones, and may even be a little snappier. The reason for adding this support is that the basic displays seem to be in short supply at times, and the Enhanced ones make a fine substitution. The firmware is bundled in a zip file on the downloads page.

1.3.0.4 Firmware Update #

September 28th, 2021 – v1.3.0.4 Update (ARDUINO AND DISPLAY UPDATE)

FIXED: Sometimes ALTITUDE selection non responsive due to floating EEPROM values.
CHANGED: WT G1000 NXi support no longer automatic, instead toggled in Settings > Aircraft on the Echo. Please note that the NXi is in beta and some bugs with it are expected. It is recommended that you DISABLE the NXi support while flying non NXi airplanes.
FIXED: Class Echo now shows up as “CLASS ECHO” in SPAD neXt serial monitor.
