Hello.

I've got a new OpLink. When it arrived at the mailbox I opened it, plug the antenna, click Upgrade&Erase, USB, all perfect; go to GCS Oplink tab, set 56700, tic in coordinator, TXPower 100%...
Save, disconnect, reconnect... and nothing.

Blue and green light solid. Each 7 seconds two orange lights flashing twice while blue off. No TX, no link.

Device Admin in Windows7 refresh one an another time trying to detect hardware, but nothing appears.

I don't find led meaning anywhere.
It's a faulty hardware?
do I call the shop?

Thanks in advance.

What appends if you connect Oplink alone (without another board connected) ?

You should see "Oplink" in right/bottom corner and Oplink tab in config.

I always plug it in alone. After Upgrading/erasing it appears as usual. But when setting transmission power to any value except 0 and rebooting It stops appearing in device list in Windows, and of course in the GCS device list neither  in the GCS Config tab (left down button) (Tried it in 4 different computers). Only LEDs behaviour described before.

I have another OpLink that works perfect whit the same procedure, Laptop etc.

The shop is 400km away, if I have to send the oplink back to them is by mail. So I want to be pretty sure that is not something I can't fix before trying warranty.

THNKS.

Never see an issue like that. If another Oplink works perfect the issue is related to a faulty device.
Something hot on pcb ? maybe a faulty RFM22 module that fail when transmit ?
Try powering with external +5v ?

Look if you see a bad join / short on RFM22 pcb side

I have same or more  issue on my Oplink mini module

firstly plug module to pc and I have see configure menu and change some parameters and save no problem

module blue led slow flash and yellow always lit

my revo board works perfect and upgradet  and no any problem

Hi,

Why do no use the last LibrePilot 15.09 release ?

A slow flashing led should say you have updated bootloader (usually not needed) but no firmware.

The procedure for Oplink is :

1 - Disconnect Oplink
2 - Hit button "Update & Erase"
3 - Connect Oplink
4 - Wait firmware update and board reboot
5 - Oplink remains connected

The only stuff active with Oplink alone is his config tab and bottom/right corner say connected.


Firmware tab is empty and should be populated by the remote device (Revo for example), when doing the link the Oplink is transparent.

[ekrem]

thank you for fast reply

I used your GCS 15.09 too no any success (last Night)

but I cant  see any oplink USB driver/com port in windows device driver screen

"connect oplink" mean remove usb cable or only click connect/disconnect button

when Oplink update or configure need other power source whit USB power

and I am re flashed your bu_oplinkmini.opfw firmware it is okay


I will trying your comments

thanks again

To use OPlink modem the firmware version on OPLink modem must agree with the firmware on flight controller.

Never ever, set non-zero power in OPlink section when antenna is not connected. Doing so may damage your transmitter or receiver!!


Start with flight controller (OPlink should be disconnected from USB), only flight controller connected to USB

• Make sure firmware is the same as GCS version
• Go to OPLink icon and enable "coordinator" then set power to something small, I set 6, but again antenna MUST be connected before doing that. Powering transmitter by setting none-zero power and not having antenna connected may damage your hardware. Then click save.
• Unplug USB, which should power off flight controller, given that no other power source is connected. You do that to reboot board.
• Plug it back and when GCS connects, you should see in OPlink section the device id, copy it, you need it so OPlink modem knows to whom to connect.[
• Unplug USB, which should power off flight controller. You do that to completly power off flight controller for now, while you will be setting OPlink modem. They shouldn't be connected at the same time.

Now you can configure your OPlink modem

• In GCS go to Firmware section and press upgrade & erase
• Now plug USB connection with OPlink modem, given that Revo is not connected and not powered at this moment.
• GCS should flash your OPlink modem and reboot the board.
• Antenna must be connected before doing this. If it is, go to Oplink section, past device ID of the coordinator you want to connect to and set power same power as on Revo, Save.

Done. Now unplug OPlink modem. Then power up your FC with a DC voltage from regulator or whatever you use on aircraft to power it with (not the usb from the same laptop) and finally connect with USB cable OPlink modem again to your laptop. It should connect with flight-controller. Flight controller must not be connected to the same laptop via USB at the same time when you use OPLink modem.

I am re flashed bu_oplinkmini.opfw from your site

Remember the bu_file.opfw is only the bootloader, without a firmware flashed the oplink do not work and no connection.

After you flash the bu_file you need this:
1 - Disconnect Oplink
2 - Hit button "Upgrade & Erase"
3 - Connect Oplink
4 - Wait firmware update and board reboot
5 - Oplink remains connected

thank you
my problem solved whit your helps
Oplink updated okay
thanks

now is a binding modems step

[ekrem]

modems binding is okay

but I cant calibrate tx stick
revo modems configuration screen pic attached

How I can do it

[f5soh]

what do you want to do ?

Oplink on RcRadio for Rc control ?

[ekrem]

yes rc control

[f5soh]

Look this video and description for PPM only:


You can also upgrade to LibrePilot 15.09


Oplink Rc side as coordinator. Flexi port with PPM from radio
Revo side as slave

****************************************­******
Oplink PPM only setup - Rc transmitter module -
- set channel range
- set power
- no need to set baudrate, is 9600 for PPM Only
- check "PPM only"
- set as "Coordinator"
- save and reboot
- note Oplm ID

****************************************­******
Revo setup - Receiver
- set channel range
- set power
- no need to set baudrate, is 9600 for PPM Only
- check "PPM only"
- set OPLM ID - Rc side - previously noted
- save & reboot
- power Oplink, Revo display Connected

Hi Laurent

thanks for all helps oplink vehicle control okay
tx stick calibration okay but not motor arms till this time

btw, when I testing rc stick  in Revo calibrate screen channel blue bar
is slowing(2second late)  move so not moving channels bars whit tx stick same time
is it normal?

sorry for english
