Ninebot Max Error Code 32
"IoT Heartbeat error."
Though this error shows as "Undefined" in the Ninebot App, it has been revealed to be a rental firmware-only code.
This code is caused only when a scooter is on rental firmware and can no longer detect the IoT device.
Be wary of buying any devices with this error code as they have a high likelihood of being stolen.
Proceed only if the seller has papers or some kind of document proving ownership.
Flash retail firmware to the scooter.
