I'm developing an Android app which communicates via BLE with an external module, and I am trying to set the BLE connection PHY. I've tried calling the method gatt.setPreferredPhy(txPhy, rxPhy, phyOptions) with all the different phy type integer arguments (for both tx and rx), and added the appropriate integer argument for phyOptions in case I was requesting a coded phy.

Every time the onPhyUpdate callback is invoked with a status 6 = GATT_REQUEST_NOT_SUPPORTED.

All other GATT callbacks are invoked with a status 0 = GATT_SUCCESS.

My permissions:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The Android device spec, according to nrf connect:enter image description here

The datasheet for the bluetooth module I'm communicating with:

Well, the error says that your peripheral (the Renesas) doesn't support this particular GATT request. I quickly scanned the Renesas doc and I couldn't find any confirmation that it support 2M phy....
