CC2540 stack integration

Other Parts Discussed in Thread: CC2540, CC2640

Hello All,

We have opted CC2540 bluetooth chipset that has to be integrated with msp430 controller and since it supports ios and android devices. And I downloaded CC2540 stack from TI website.

Our requirement is to advertise the bluetooth device and connect to the requests received from ios or android mobile and send the battery voltage connected to the msp430 controller to the connected device.

My question is :

Do I have to write the application and flashed to the BT module or can I use the source files of CC2540 SDK and integrate in my MSP430 controller through UART or SPI?

Is CC2540 is dedicated to 8051? As I read , it is compatible with msp430 controller also. If it is, then do I have to change pripheral.c file for msp430 controller?

Regards,

Sowmya

I'm not entirely sure what you are asking. The CC2540 is an 8051. There are no other options there unless you want to use the CC2640 which is an ARM.

If you want to communicate serially (UART or SPI) with an msp430, I would recommend looking at the serial bridge example: http://processors.wiki.ti.com/index.php/SerialBLEbridge_V_1.4.1

It sounds like you could also use an overview of the SDK. I would recommend reading through the software developer's guide included with the 1.4.1 installer.

Hi Tim,

We are using a module using cc2540 chipset. And I read software document of cc2540 and there are 2 modes: single mode and network processor mode. We need a network processor mode and will communication through HCI commands over UART.

One more question is:

Do I have to program the HostTestRelease project in cc2540? Does this project will be able to visible to android and IOS devices when I give advertise command?

Hi Sowmya,

You can use the HostTestRelease application on the CC2540 and send HCI commands over UART from an external MCU like MSP430. You have to program the HostTestRelease application in the CC2540.

Thank you Kavitha. This is what I wanted. And one more question:

As per document, HCI commands consists of type:opcode:Datalength:Data.
1) Do I have to form the packets for each HCI command and send it through UART? Or
2) Can I use HCI prototypes declared in hci.h?

If you are telling to use 2nd option, where are the UART buffers declared and functions to transmit packet through UART?

I am using this module for the 1st time. Please clarify my doubts.

Regards,
Sowmya
