CC2564MODN: BLE mode

Part Number: CC2564MODN

Hi,

Good Day. I have a customer who is working with CC2564MODN. Please see below his query for your reference. Thank you very much.

We need to make measurement of the BLE signal transmitted at the output of the CC2564modn module.

In order to measure the signal strength  we hook-up the module to an SMA cable and connect to spectrum analyzer for measurements.

We were able to make measurements by putting the module to transmit continuously in classic Bluetooth mode (BDR/EDR).

In classic mode there is no connection to a master, the connection  is not possible, since we don't have an antenna, it is replaced by a connection to an SMA cable.

1- How can we make the module transmit data in BLE mode, without a master connection ?

2- We want also  to control the Dwell time in the same setup ?

Best Regards,

Ray Vincent

    Hi Ray,

    1. You can transmit in BLE using the HCI commands discussed in BLE Testing > Transmitter test in this guide: 0451.CC256x Testing Guide - Texas Instruments Wiki.pdf

    After downloading the service pack to the device and enabling Low Energy, you need these two commands (you may need to modify the parameters for your use case):

    Send_HCI_VS_Set_LE_Test_Mode_Parameters 0xFD77, 0xF, 1, 0, 0x71764129, 0, 0, 10, 20, 0, 0

    Send_HCI_BLE_Transmitter_Test 0x00, 0x00, 0

    2. I'm not familiar with Dwell time. Perhaps that can be modified with one of the parameters here:

    Thanks,
    Jacob
