CC2564MODNEM - SPPDemo - No device found

Hi all, first post here.

I am trying to add BT connetivity to a project and wanted to try the CC2654 product. But I am getting stuck in the SPPDemo. Here's the setup :

A TIVA C Launchpad (TCM4C123GHPMI7...) is connected to a CC2564MODNEM board (not CC2564B for what I know) using custom connexion :

BT_RX <-> TIVA UART1TX
BT_TX <-> TIVA UART1RX
BT_RTS <-> TIVA UART1CTS
BT_CTS <-> TIVA UART1RTS
BT_nShutd <-> TIVA_GPIO_C6
Also 3.3V and GND are connected on one pin each.
PCM and slow clock pin are left unconnected
I DO have made a few changes in the code accordinlgy to this connexion (in file HALCFG.h and HALCFG.c) and the UART link seems to be working just fine.

I want to connect this to an android phone (samsung galaxy S II GT-I9100, cyanogenemod 12.1, android 5.1.1 : no BLE inside)

I am using the Bluetoia stack V1.2R2.

I am working with Keil uVision4. I went from a scratch project trying to mimick the demo project, but adapting it to the tiva launchpad.
Compiling flags are :
PART_TM4C123GH6PM, TARGET_IS_BLIZZARD_RB1, DEBUG, DEBUG_ENABLED, DEBUG_ZONES=DBG_ZONE_ANY

Compilling, linking and connecting to the debug com port runs smoothly.
Following this tutorial : processors.wiki.ti.com/.../CC256x_TI_Bluetooth_Stack_SPPDemo_App
I launch the demo as a client and intend to connect it to an android phone using blueterm.
As you can see in the following debug log, I don't manage to detect any BT device from the client.
I know from my phone there are a few. The said phone is not detected either.
And my phone can't see the CC2564 module, even if detecting other devices around.

Sooo what can I made wrong ? Missing flags ?

Thanks for your help.

Hi Antoine,

As mentioned in the datasheet, the CC2564MODN is a module based on the CC2564B IC. So you need to make sure that you are selecting patch for the CC256xB in the BTPSVEND.c and not the CC256x.

Best regards,
Vihang

Hi Vihang, and thanks for your time.

Why didn't they call it the CC2564 - B - MODNEM ? :P
Indeed I missed that part. I switched task and cannot test that right away, but will keep the post updated when I do.

Cheers,

Antoine

Yep, okay, that was it !

Adding the flag "__SUPPORT_CC256XB_PATCH__" resolved everything.
Build and link without issue. And finally seing other devices. Also the SPPDemo worked.

Small note : the screenshots of the wiki shows the LE version of the server, but it is still workable.
(there : processors.wiki.ti.com/.../CC256x_TI_Bluetooth_Stack_SPPDemo_App

Thanks again for the little push.

Hi,

I am also working with CC2564MODNEM. Can you please tell me how to include __SUPPORT_CC256XB_PATCH__ ?

thanks,
Sooraj

It is quite literraly this statement :

#define __SUPPORT_CC256XB_PATCH__

Or adding the "__SUPPORT_CC256XB_PATCH__" flag into your project defines in your favorite IDE.

So, I just need to add the line to BTPSVend.c before debug?

0 Antoine Bax de Keating85 over 8 years ago in reply to Sooraj Gopakumar

Prodigy 70 points

No, I'd do it in the first file compile, so the one having the "main" function in it, before including anything else. It can be the "main.c" in non-OS in my case.
This is also why putting it in the projects flags in the IDE (or actually in the compilation flags) is a better solution. You don't have to find the optimal place for this include :)

0 Sooraj Gopakumar over 8 years ago in reply to Antoine Bax de Keating85

But in the Bluetopia wiki documentation, they have asked to include this line in BTPSVEND.c.

processors.wiki.ti.com/.../CC256x_MSP430_TI_Bluetooth_Stack

Actually, I am getting Stack init failed: -4 error. I recently discovered that my pin allocation was wrong. But, even after correcting the mistake, I am still getting the same error. I was wondering if it is because I did not include the patch.

0 Antoine Bax de Keating85 over 8 years ago in reply to Sooraj Gopakumar

The __SUPPORT_CC256XB_PATCH__ flag is only to match the chipset you are using. (CC2564B needs it)
Sorry, I don't know this -4 error.
You'd better create a new thread if you want to get proper help with this one.

Hello Sir,

Can you please tell me the frequency of the crystal that is giving clock to MSP? My board has a 32.768 kHz crystal. I am feeling that would not be sufficent.

thanks,
Sooraj

Hi Sooraj,

As you could have read, I was not using a MSP chip but a TM4C123 on a Tiva Launchboard.

Please make your own thread for this kind of question. You will have more success in getting attention from people able to help you.
