Unable to connect to Fitindex ES-26M

[pinusc]

Hello, I purchased a fitindex ED-26M because I saw it was on the supported scale list. My model looks exatly like the one pictured in the wiki. The scale won't show up in the bluetooth devices; I am also unable to pair with the Android bluetooth interface. I tried:

• connecting with openScale
• uninstalling and reinstalling openScale (making sure data was wiped)
• installing dev version of openScale

Then I tried pairing with the official app, which went smoothly. The scale still does not appear as a bluetooth device on android.

After delving within the logs of the official fitindex app, I believe I found the MAC address of the scale (which I was previously unable to even through linux, as I live in a very bluetooth-polluted environment). Attempting to pair/connect to the device on linux or android (which I could try after finding the correct MAC address) has been useless.

I think the problem here is that openScale checks for the advertised name of the bluetooth scale; the expected name for this scale (as in BluetoothFactory.java) is "QN-scale"; however, my scale does not advertise any name, presenting itself only as a MAC address. In wireshark I can see some HCI events generated by this device, so I think you don't need to pair/connect to the scale in order to receive events, and that's what even the official app does.

I know very little about how Bluetooth/BLE works; would it be possible for openScale to read events without pairing to the scale? Why did this use to work with the same model and now doesn't?

please attach the openScale log file and please don't do a Bluetooth pairing with the Android system

Hello,

I'm having the exact same issue. The scale is recognized immediately by official application, but neither openscale, android standard Bluetooth stuff nor ble scanner can see it.

My scale is branded as a Renpho ES-26M,but it look exactly the same. I've included logs from openscale and a screenshot of ble scanner. My scale is turned on and I'm standing on it while doing my tests.

I have the same result on my Mi 9t and a Samsung galaxy s7.

Do you what is happening and how can it be fixed?

I'm having the same problem as @canu1337. I have a Renpho scale, model name is es-26m-w and on the back it has also written "cs20m" as it's fcc-id.

This is the log:

I'm happy to help out somehow, I already tried digging through it with wireshark and started some guesswork, but im not sure how to continue.

Same issue here, OpenScale smoothly works with ES-CS20M (V1) but not with ES-26M.

For the es-26-m model, here is a sample bluetooth packet. The f9 24 in the payload is the weight.

Relevant to detecting this is probably also

BD_ADDR: ed:67:39:c6:1d:b5 (ed:67:39:c6:1d:b5)
