I've been having issues with Firmware 3.10.
The morning after updating it, flew the P2V+ until depleting one batt. I took it down and then replaced the batt for a charged one and it was just after finishing the start sequence that the "MC: Invaild Battery" legend came up in the VISION App. Replaced it for another charged one and same story. GPS starts, the camera works, gimbal levels, gets 13 satellites but there's no engine start.
Checked out YouTube and forums and some said it had to be something with the small spring connectors at the battery bay. That wasn't my case.
When I connected the phantom to my Mac, the Assistant Software alert said that my battery wasn't valid. Downgraded the Firmware from 3.10 to 3.8 as adviced by DJI and upgraded the Assistant Software by downloading the 3.8 version straight from DJI's website. Also read that someone had issues with the iOS VISION App 1.0.46 and waited for DJI to release the latest version - as they said through a pop up in the App - which they did just a few hours ago.
Already updated the iOS VISION App App to 1.0.48 and I am still getting the "MC: Invalid Battery" message.
Any ideas?
