Ninebot One A1/S2 is not founded, because uses another Service UUID (FEE7) and characteristics:

• FEC7 (CBCharacteristicProperties.Write)
• FEC8 (CBCharacteristicProperties.Indicate)
• FEC9 (CBCharacteristicProperties.Read)

This is no problem, but no getted headers (SN, etc.).

May be have choice get all firmware data for debug?

KingSong 16B FW 1.27: the crurent is signed. The highest weight bit is used to set the current sign.
This lead today to incorrect current, then power, then energy.

On KS/Gotway wrong calculating total distance.
130 real km = 376045570.0 in app.
let totalDistance = Double( (Int(buffer[6]) * 256 + Int(buffer[7]))*65536 + (Int(buffer[8]) * 256 + Int(buffer[9])))

Tests:
On my tests KS14 rides 137km (by official app metrics).
Value of buffer:
buffer[6] = 2
buffer[7] = 0
buffer[8] = 106
buffer[9] = 22

Gotway MSuper V3 rides 8.4km
Value of buffer:
buffer[6] = 64
buffer[7] = 0
buffer[8] = 28
buffer[9] = 32

Nice source! You can add changing Serial Number?
Tip: If you have Ninebot One E and change Serial Number on "N1OP...", max speed will be ~30 km/h

On Gotway (exclude MCM4) wrong calculating temperature. Tested on ACM, MSuper V3, Monster.

219 value app ≈ 20 °C

Hi!

With V3.0 in KingSongAdapter.swift you divide a second time the current by 100:
current = fabs(current / 100.0) // I have problems with sign in some wheels

Any thoughts?

I checked "One Fun Bool". You know what function it performs?

Changing max speed is not working. Ninebot One E on 1.3.5 limiting max speed on ~22 km/h. I set max speed on 30 km/h via 9Metrics (TestMode), reset Ninebot One, but it's not works - limit also ~22 km/h :(

How about changing the pin code?

Need add method for On/Off limit speed mode, and On/Off lock mode.

I did complete methods for getting values:

    func limitMode() -> Bool? {
        let v = data[BLENinebot.kvFlags].value
        if v == -1{
            return nil
        }

        return (v == 9 || v == 11)
    }

    func lockMode() -> Bool? {
        let v = data[BLENinebot.kvFlags].value
        if v == -1{
            return nil
        }

        return (v == 10 || v == 11)
    }

And need include kvFlags in listaOpFast array

About values kvFlags:
8 - normal,
9 - limited,
10 - locked,
11 - limited & locked

Project doesnt work with newer version of xcode, and trying to upgrade to swift 4 or 5 breaks the code.

Im not that familiar with iOS development to make a fix and a PR.
