8 years ago The MEGA64 version of er9x has insufficient flash space to add this. It should be possible on the '128 version.

8 years ago Could it fit in a new version removing FrskyD protocol and replacing with LTM?

8 years ago The problem then is it adds a number of extra builds as there are several languages to consider as well as the option of original or serial voice. These all need building, testing and releasing. Can you compile the source yourself?

8 years ago Yes, I guess I could do. And test it. Thx.

7 years ago I am for the idea of LTM telemetry support in er9x. I also have M64 based radio, so unfortunately I also support the idea of creating another build version without FrSky telemetry. Looks like LTM is becoming a standard for telemetry https://github.com/ShikOfTheRa/scarab-osd/issues/219

6 years ago LTM support please . Im trying so hard to do it myself but i'm facing compiling errors . Also i'm still a beginner in coding :D
Feature request to include native LTM (Light Telemetry) support in er9x.
LTM fits low baudrates like 1200/2400 bauds over long range transmission like OpenLRSng transparent serial link, or FSK modem trough fpv Video TX Audio channel.
LTM is supported by Cleanflight, INAV, amv-open360tracker, Gettostation and other platforms.
Here a link to infos on LTM:
https://github.com/stronnag/mwptools/blob/master/docs/ltm-definition.txt
https://github.com/iNavFlight/inav/wiki/Lightweight-Telemetry-(LTM)
And here a definition from Cleanflight doc on telemetry:
"LTM is a lightweight streaming telemetry protocol supported by a number of OSDs, ground stations and antenna trackers.
The Cleanflight implementation of LTM implements the following frames:
G-FRAME: GPS information (lat, long, ground speed, altitude, sat info) A-FRAME: Attitude (pitch, roll, heading) S-FRAME: Status (voltage, current+, RSSI, airspeed+, status). Item suffixed '+' not implemented in Cleanflight. O-FRAME: Origin (home position, lat, long, altitude, fix) In addition, in the inav (navigation-rewrite) fork:
N-FRAME: Navigation information (GPS mode, Nav mode, Nav action, Waypoint number, Nav Error, Nav Flags). LTM is transmit only, and can work at any supported baud rate. It is designed to operate over 2400 baud (9600 in Cleanflight) and does not benefit from higher rates. It is thus usable on soft serial."
