No services discovery with Master Control Panel on android 5.0

[aferchichi]

We are currently developing an Android app (5.0) supporting the peripheral mode and communicating with the Master Control Panel (v3.7.1).

The connection to the Android smartphone is well established but the Master Control fails to make the discovery of services on the device.

All is well between a central Android or central iOS and our Android application. more we tested with the android application "NRF Master Control Panel" and the discovery of various services is done properly.

We tested with other applications supporting the peripheral mode and Master Control as central. The problem of services discovery still exist.

Hey.

Does the problem appear on the windows of android version of Master Control panel? (You write Android in the title, but only windows has v3.7.1)

Can you describe better what happens when service discovery fails? Does it crash? Does it return an error? Does it discover some services but not all? Does is discover no services, but seems to work fine otherwise? Can you upload a screenshot?

Hi,

The problem appears on the windows version of Master Control. The peripheral is the Android application. No there is no crash but the discovery finishes without any results from the windows version but it works well from the Android version of Master Control (nRF Master Control Panel) to our peripheral Android app.

The 2 screenshots attached show the result of discovery services from an Android Master Control app (success) and from the windows version (failure)

It seems the problem lies with Your windows master control panel (MCP). Try to uninstall and install the latest version (v3.10.0). Which nRF dongle are you using with the MCP? Try to flash the firmware on it again after installing the newest MCP.

Hi,

• The application we used on the peripheral is "BLE Peripheral Simulator" play.google.com/.../details

• The device we are using is "ZTE Blade S6", Android version 5.0

• When we use Master Control Panel v 3.7.1, we can't see services published by the phone. However, with a central android application "nRF Master Control Panel" (play.google.com/.../details all works well,

Thanks !

Hi. When i find a smartphone that supports peripheral mode, i will try to reproduce your results. In the mean time i advise you to update MCP and see if it makes any difference.
