CC2564MODA: HCI Command sequence for BLE central device

Vishal Nandanwar
Intellectual 550 points
Part Number: CC2564MODA


Hi,

Note - this is an repost

I am working on a existing product in which I have to integrate the BLE functionality. We have selected CC2564MODA module for the same, BLE stack will reside on my MCU as CC2564MODA is not having his own MCU. Existing MCU is not supported by the TI hence I need to implement the HCI command layer in my code so that communication with the CC2564MODA should be feasible.

I am not sure of command sequence required to initiate the CC2564MODA so that it can act as BLE central device.

I did some research and tried to find the command sequence. But i am not successfully able to discover the peripheral devices around me.

Bit more information about my problem - I am developing a BLE Central device (IoT gateway) which will discover the peripheral devices around it and will communicate with them using GATT protocol. For this I have to use HCI command sequence only as BLE stack is non portable on my MCU. This is as existing product in which I am adding BLE functionality hence can not use MSP430 or any other MCU in between. We have selected CC2564MODA module as BLE transceiver.

I am using HCITester application to send HCI commands. I have also initiated the CC2564MODA module using TI init scripts v1.6. Below is the script which I have created. Please have a look and let me know the corrections required in this script.

WaitForAllEvents 50000, True

I am not getting the LE advertising report from the CC2564MODA module.

Please let me know whether my approach is correct or not? as well what command I am missing here?
