      If the error “Failed to access the drone’s information” is prompted, it’s because your drone is either not connecting to 4G or losing GNSS positions. Please check your 4G connection and bring your drone to an open field with good CNSS position signal.

      If the GNSS positioning signal is good, the 1st light indicator will be in green. If the 1st light indicator is in red, the GNSS positioning signal is bad.

      Usually if it’s the first time adding the drone, the drone needs to report its physical location to the remote cloud server for security check. Thus, the drone needs to have GNSS position, which means it need to be brought onto an open field, for getting better satellites broadcast signal.

      Set device name and press confirm

      How to use ACS2 2021 as ACS2 2020

      If you want to have ACS2 2020 but you only have ACS2 2021 in your hand, you can use the following method to change ACS2 2021 to ACS2 2020.

       

      For example, this method is very useful when sometimes we want to update XRTK4 firmware using ACS2 2021. As we know previously, XRTK4 firmware update need to use ACS2 2020, so we can change the firmware ACS2 2020 to ACS2 2020 since they have the same hardware. We first downgrade ACS2 2021 to ACS2 2020, update XRTK4 using ACS2 2020 and XAG Agri 2 App, Update ACS2 2020 to ACS2 2021

      This method is only used under XAG Technical Team advice. Change ACS2 firmware between the version 2020 and 2021 has some unknown risks that may damage the device.

      Before ACS2 2021 downgrade, please check if

      • ACS2 2021 can access 4G network (insert 4G SIM card into ACS2, check if the second light illuminate in green)
      • ACS2 2021 can turn on hotspot (you may need a smartphone and laptop to check this)
      • ACS2 2021 firmware list (it’s better to take a screenshot)

      Brief Process:

      Procedures:

      Step 1: Reset ACS2 hotspot, quit ACS2 LNT mode (if applicable)

      ACS2 WIFI hotspot cannot be found after linked to LNT.

      If your ACS2 haven't been linked to LNT, please ignore

       

      Question: How can we possibly know if your ACS2 is linked to LNT?

      Answer:

      Check if the 5th LED indicator light is illuminated in either green or yellow

      Check if you can find the ACS2 hotspot

      Question: How can unlink ACS2 from LNT and quit LNT mode?

      Answer:

      long press button A until you hear the AI voice prompt and the 5th LED indicator light become dim.

      Make sure that the 5th LED indicator light become dim. If yes, your ACS2 remote controller has been reset successfully.

      Next, use your smartphone WLAN to search ACS2 WIFI hotspot
