Part Number: CC2640R2F
Other Parts Discussed in Thread: LAUNCHXL-CC2640R2, BLE-STACK, CC2640

Tool/software: TI-RTOS

Hi friends,

I'm implementing new things on my CC2640R2F LAUNCHXL. I have tested the Project-zero very well and it works really well, even with my customized APP. Now I would only like to take care of my devices. Is it possible to make them communicate with each other? In a nutshell, I would like to make such a communication:

From device 1 I click the button and on device 2 the LED lights up.

Do you have suggestions?

I suppose you can implement this based on simple_central and simple_peripheral. You can run simple_central on one LAUNCHXL-CC2640R2 and simple_peripheral on another to do it.

Hi YiKai Chen , I was just reading these two examples. But I also saw that I only have one of 7x7, because I loaned the second to a friend of mine. On the other hand I have two CC2640R2F 4x4, but inside the examples there is no board.h to modify. How can I do?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

You can revise LaunchPad board file according to your 4x4 custom board to make it work.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

In the example there is only the code board.c. Where can I find the board.h code?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Board files are under SDK installation folder\source\ti\boards\CC2640R2_LAUNCHXL

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I modify the board.h and another files of CC2640R2F but not works. On the terminal I don't see nothing

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

What do you mean “On the terminal I don't see nothing”?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I'm following this guide: dev.ti.com/.../

Now, I connect the my CC2640R2F LAUNCHXL, but I don't see nothing on the terminal. Here shows the variuos string

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Do you use latest SDK?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

yes

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Do you mean you don’t see anything output on UART even you test it with LAUNCHXL-CC2640R2?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

with my 4x4. I modify only CC2640R2_LAUNCHXL.h for my 4x4 device

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

If you test UARTecho example, does it work?

Hi Mark,

Did you see the BLE-Stack User's Guide on this topic? dev.ti.com/.../custom-hardware.html

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I used the my custom 4x4 for another examples such as: PinInterrupt, ProjectZero and EasyLink. These examples have the files board.h, CC2640R2_LAUNCHXL.c / h inside their folder, I modified those and they work. But this doesn't work for me.

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

What do you mean "I modified those and they work. But this doesn't work for me."?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I modify these code with my old examples and it works, If I modify this file with simple_central and simple_peripheral not works

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

If you use simple_central and simple_peripheral in blestack of simplelink_cc2640r2_sdk_2_40_00_32, I suppose you have to modify board files under C:\ti\simplelink_cc2640r2_sdk_2_40_00_32\source\ti\blestack\boards\CC2640R2_LAUNCHXL.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I modify this that you told me, but not works

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Can you elaborate the UART pin that your custom 4x4 chip uses and what modifications on board files you made?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I commented on the lines with PINs greater than 10 and added mine.

RX 1
TX 2
DIO 5 LED
DIO 6 LED

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Can you post your exact code?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

CC2640R2_LAUNCHXL.rar

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

If you use LAUNCHXL-CC2640R2 and change UART_RX to IOID_1 and UART_TX IOID_2 in board file, does it work?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

With my CC2640 4x4 doesn't works

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

No idea. Can you use LAUNCHXL-CC2640R2 and change UART_RX to IOID_1 and UART_TX IOID_2 in board file to see if it works first?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Yes It works with LAUNCHXL

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

If the same FW cannot work on your custom 4x4 PCB, it should be HW problem and you should check your custom board.

0 Marie H over 7 years ago in reply to Mark Felberg

TI__Guru* 83691 points

Hi Mark,

You should be able to use the 4x4 board files found in C:\ti\simplelink_cc2640r2_sdk_3_10_00_11\source\ti\blestack\boards\CC2640R2DK_4XS .

You should also check out the hardware design guidelines: http://www.ti.com/lit/swra640

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

The my custom boards it works with ProjectZero

0 Mark Felberg over 7 years ago in reply to Marie H

Guru 19990 points

Hi Marie, I created the my custom board code for the my projectzero and it works. Now with the same code for this example, not works

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Do you mean you can see UART output from ProjectZero?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

yes

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

What example do you test and UART doesn't work now?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Simple_peripheral and Simple_Central

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

When you test Simple_peripheral on your 4x4 custom board, can you see it sending advertising?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

How?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Use sniffer or SimpleLink Starter APP to scan it.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

The SimpleLink Starter not see nothing

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

I suspect you modify something in your SDK/examples and cause this issue. I would suggest you to remove and reinstall SDK to test again from scratch.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I re-install the last SDK for my CC2640 4x4 custom board. I try the first time with my LAUNCHXL and it works and the second time with my custom board and not works. I modify only CC2640R2_LAUNCHXL.h under simplelink/source/ti/boards/cc2640r2_launcxl in this mode:

If you build ProjectZero using this board file, does it work on your 4x4 custom board?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

yes

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Oops... Do you mean you can see ProjectZero sending advertising on your custom 4x4 board but simple_peripheral doesn't?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

yes exactly

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

That's strange. Run out of idea...

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Can you try with your cc2640 4x4?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

Do you mean CC2640R2F 4x4?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I resolve the problem. You told me the wrong path for board.h

You told me that I should to change the board.h under ti\simplelink\source\ti\boards\cc2640r2_launchxl but this it wrong. For to change the pin 7x7 in 4x4 I should to change this board.h under ti\simplelink\source\ti\blestack\boards\cc2640r2_launchxl

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735695 points

I check my previous reply and I actually told you to modify board file under C:\ti\simplelink_cc2640r2_sdk_2_40_00_32\source\ti\blestack\boards\CC2640R2_LAUNCHXL. I think it's your own careless...
