Dear Dialog Team,
We made a prototype simple BLE tag based on DA14585. The antenna part is a direct implementation of your DA14580-RD-WLCSP-SMTag2-VC. I attached the schematic pdf of your design file for your reference. We are trying to do FCC/CE certification and are in contact with a certification vendor. Following are the queries he has raised:
1) Can you provide technical details on the antenna used such as gain of the antenna, etc? Also, can you please explain why there is antenna trace on the bottom layer also since generally, PCB antenna trace is only on one layer. Is it for better grounding??
2) Is the reference design certified, since we are using the same antenna part?
3) Can you provide with certification/Test firmware, software & documents necessary for the certification process?
Thanks & Best Regards,
