Does anyone happen to know which RSSI pin goes to which antenna? I'm thinking I will grab the RSSI from a patch antenna and run a CP antenna for the close in stuff, or do you need both RSSI values for the tracker to work?

Yes, you need both antenna to be directional so the tracker know witch way to turn. It will turn the stronger signal way.

Could this be used with a continous motion servo? Would you have to modify the code?

that i don't know

Hi thanks for uploading this. I wanted to know if you could help me. I believe I have everything setup like yours, except for using a different firmware on the pro58, but the servo only spins one way. It spins continuously and doesnt seem to respond to where the tx is transmitting. Ive installed firmware in Arduino before but I am definitely a noob with it. I appreciate any help you could give.

So i just finished building it. it seems 90degree off, have you made any adjustments in the Arduino code?

for me it worked without adjust... that is notice that your model need to be a little bit out so the tracker start working better.

Ok, i made it finally work!
I had to change the servo position in the arduino code to -1 instead of 1, adjusted the servo endpoints via debuging commands in the code and tried it in a room.
Yeah not that great at very close range :-D
Do you using the EXPONENTIAL or SIGMOID tracking method ?
Besided that, everything is workin! It was the best idea made it out of Pro58 ;)

Hello, what did you change in the code, I dont understand what you mean about servo endpoints.
Regards

servo endpoints means that the servo will not jitter when it will reach the end, if you are using 180 servo and not 360 deg

can't remember now, but if you go through the code you will find some debug lines commented out, enable them and depending on which command you enabled you can see it in terminal logger in Arduino. it's long time ago and i know i had lots of trouble configuring it

Yeah already got RAW data from debug, I need to adjust this values.
Already change the servo direction, analog rssi pins and no sucess, so the problem is in the RSSI_MIN and MAX adjustments.

I don't know anything about EXPONENTIAL or SIGMOID tracking method :D but it would be nice to see how and what you changed.

Good Ideas, anyway what is rssi pins for this pro58??? pin 4 from the right???

update the pinout

great idea. You could put a diagram of how is the installation of components inside the box, thanks

So, looking at the pinout, you are powering the pro58 from BEC on +5V and GDN, then GND and VIDEO to the yellow connector? Or you don't need GND for Video Out?
Is that correct?

i also use GND for video

Can you share how to output video from pro58? Or maybe a link on how to do it?

i added pinout picture

How about the pinouts for RSSI?
Did you desolder everything to tap into rssi pad?

Hey there, great little project you have,
I'm trying to print just the lid to cover the module on top of a fpv screen. Would you be able to upload the lid as a separate file and if possible the original file so I can trim out the 'skirt' section around the cover.
Pic added for reference.
Thanks in advance :)

Thanks for the tip! Files added!

HI there :) Great project! Is there anything i need to change to the code to make it work with the pro58? as in the rcgroups post you used the RC540R diversity. Im really eager to build one myself to make a neat Groundstation with the pro58 and achilles firmware. Keep up the good work :)

don't need anything else, just solder the rssi wires

Pinout for the rssi solder points? Or did you desolder everything?
