CC2640R2F: LAUNCHXL-CC2640R2 advertising is not seen when using SmartRF Studio 7

Part Number: CC2640R2F
Other Parts Discussed in Thread: LAUNCHXL-CC2650

Hello,

I am using LAUNCHXL-CC2640R2F board and trying to see it on smartphone with BLE scanner.

When flashing the board with BLEPheripheral hex file it can seen on the phone, but when using SmartRF studio 7 and initiating "packet Tx" I cannot see the advertising on the phone.

I changed the BLE channel to 37,38 and 39 but it still doesn't work.

I can see the packets with another LAUNCHXL and using the "Packet Rx"

I am using the default target which is LAUNCHXL-CC2650

Any ideas why it is not working?

 Thanks

    Hi Arnon,

    The packets transmitted by SmartRF Studio are not in the correct advertisement format to be picked up by BLE devices.

    Cheers,

    Thanks Fredrik,
    I also can't pick these packets by Keysight N9000B signal analyzer.
    Is there any modification that can be done so I would be able to do measurements with any other equipment rather than another LAUNCHXL board?

    Hi Arnon,

    I am not familiar with the Keysight N9000B. Is it simply demodulating the packets, or does it expect certain formats like BT PHY testers? The former you can use with SmartRF Studio. For the latter you need to run HostTest on the LaunchPad and use appropriate HCI commands to set up the right test packet format.

    Rgds,

    Hi,

    The equipment is like BT PHY testers and it expects a certain packet, they call it "reference packet", do you have any clue what they mean by "reference packet"?

    I did try to run the HostTest on the LAUNCHXL and use the HCI test commands, I can see the burst in the instrument, but it still cannot sync on them

    Thanks
