    Does AP6210 chip share BT and WiFi via one antenna?

    Anyone know if the AP6210 communicates both BT & WiFi signals via the single antenna?. I have an RKM MK802 IV, the second gen with the AP6210 chip. There is only one antenna lead, and not dual like my 1st Gen MK802IV, which had a thin wire for BT, and a wireless antenna.
    Any ideas as to where the BT ant would be, if not shared?

    AW: Does AP6210 chip share BT and WiFi via one antenna?

    Hello,

    The antenna on the mk802iv is for Wifi only.
    For Bluetooth there is no Antenna.

      Thank you, Neo. I ask because I modded the stock antenna with a new SMA connect pigtail and I have almost no BT functionality when the antenna is unscrewed from the pigtail cable. The problem is most likely related to RFI from adjacent devices. Too much crosstalk...

        Isn't the AP6210 based on the BCM4330 which does support one antenna for wifi and bluetooth?

          The Broadcom site indicates exactly that. I was curious because the BT reception would be damn near null without something to RX/TX through above the PCB. Additionally, the chip has an FM receiver! Had no clue of it's existence till this morn. Is it worthwhile? Probably not.
