Telemetry on multiple ports
« on: March 25, 2016, 07:11:08 pm »
Is it possible to output telemetry on multiple ports? Currently my revo outputs the telemetry for the osd on the receiver port, and I'd like to use my flexy port for bluetooth telemetry. (I'd like to use the oplink only for control)

Only one Telemetry port allowed.

You can connect your bluetooth module to the ground Oplink connected to radio and allow "long range" telemetry.

Hi! Thanks for the reply, but If I'm right, the oplink range is shorter if I use it for telemetry and control, or just the latency bigger for the control if using telemetry too?

Maybe some latency.

What range do you need ?

Slightly bigger than the vtx range, I think it's now about 2kms.

This range can be done using good antennas, but indeed better with PPM-Only that give extra sensitivity.

I think I'll keep using the oplink for telemetry and control, and if I need more distance just change it to ppm only and watch the telemetry on the osd :D

One more issue: Do you know why doesn't my oplink mini pair with my revo if I power it from an external battery and not an usb cable?

No, sorry. I don't have a crystal ball here :)

Post Oplink config screens on both sides

The pairing is good, it's working if I power it up with an usb cable and an external power source too (external needed for rx and bt). Maybe the voltage is too low? (it's a 1S lipo battery)

Likely too low when voltage drop using 1S
+5V or 2S battery voltage are better choices.

Hm, I think I'll use a power bank for it :D
