If there is no data to be sent in the EIR packet, i.e., eir_data is set to 0, then it means that the device does not have a device name.
For more details about this, please refer to section 8 EXTENDED INQUIRY RESPONSE DATA FORMAT from Bluetooth Specification Version 5.0, Vol 3, part C: https://www.bluetooth.com/specifications/bluetooth-core-specification.
But my phone can detect the device name

Can you please confirm if slave device is BT or BLE?
Also, can you give more product details about your slave device?
