Hi if i could get some assistance for the previous purchased GEPRC Cinelog 25 V2 analog. After installing DJI o4 Pro i’m getting a great video feed and no issues there. But low RSSI warnings are present from 3-4 Meters away. I have relocated the expressLrs Rx antenna Which has worked fine for around 25 flights but hasn’t made any difference, i have checked the antenna and ufl clip etc all looks okay, only thing i’ve done is to setup the dji o4 pro in beta flight as per the
instructions Manual for the GEPRC TAKER G4 35A AIO Flight Controller, (Uart 1 for ConfigurationMSP for the VTX) i would really appreciate your help into the matter, thanks Vinny

Radio being used: Boxer with Radio Master ExpressLRS module

Kind regards,
Repositioned the Expresslrs Antenna and checked connections

Hi Vinny good day,

Thanks for reaching out to us!

You obviously have OSD set up as everything else is coming through. I spoke with Nathan and his first question was refresh rate, if for example it is set at 1000Hz, it would report this error.

If not, these could be possible causes:

  1. Check ExpressLRS Firmware & Settings

    • Confirm the receiver firmware matches the module firmware (e.g., both are the same ExpressLRS version).
    • Make sure your region and power limits are set correctly in both the transmitter module and receiver configuration.
    • If using Dynamic Power, consider disabling it or setting a higher minimum power until you confirm stable link quality.

  2. Review OSD Settings (RSSI vs. LQ)

    • ExpressLRS primarily reports Link Quality (LQ) rather than traditional RSSI. In Betaflight, you may need to enable RSSI via Rx or display LQ instead of “RSSI” in the OSD elements.
    • A mismatch in how Betaflight interprets link data can cause the OSD to show a low RSSI warning even though your link is strong.

This is also an excellent article about the O4:

Hope this helps.
If there is anything else I can help with please do let me know?

David
