Hey. I have emu black in my car. The bluetooth works on an android but doesn’t seem to show on my iPhone 15. Is there something that I am doing wrong or it doesnt support ios devices?

In the new version, in settings, you have an option bluetooth devices. Set it to “all”. Works for me.

Hi! Thank you for the detailed information. Could you please check the following and let us know the results?

  1. Which connection type does the app use on Android: BLE or SPP? If possible, please send us a screenshot of the screen displayed after tapping the Bluetooth icon in the top-right corner of the eDash app.
  2. Before trying to connect with your iPhone, do you disconnect the CAN Bluetooth module from the Android device? If the module is already connected to one device, it may not appear at all on the other device.
  3. On your iPhone, could you please try the following steps?
    • Open Settings → Bluetooth Connection
    • Set Bluetooth Devices to All
    • Return to the Available Devices screen
    • Tap Scan Devices

Regarding the lag on Android, which Android device are you using? We have recently made significant improvements to data transmission, so there is a good chance that the upcoming eDash release will improve the situation.

Please send us the requested information and let us know what happens after completing these steps.

Hey. Thanks for the reply

It uses SPP

I used the app on my buddy’s phone to see if that works. I tried connecting it so many times with the iPhone but it never seems to show.

I tried everything and still doesnt seem to work.

The android phone that was laggy was the Samsung S24 Ultra.

If your CAN-Bus Bluetooth module supports only SPP (like older modules), unfortunately it cannot connect to an iPhone. iPhones use a newer Bluetooth connection called BLE and do not support SPP.
