Hi sir.

I have a question,

Platform: MSP-EXP430F5438 + PAN1315ETU CC2560
Demo firmware : MSP430BT5190-CC2560 SDK

The current Bluetooth identifiers of “BlueMSP430” (SPP service , from the Host) are changeable in the firmware?

then how do i change it?

thanks.

Dunk Wu,

Absolutely. Than prefix is defined in sdk_bluetooth_config.h right at the top:

#define SDK_CONFIG_DEVICE_NAME "BlueMSP-Demo"

Hi Miguel ,

I read page 138 in the Developer's Guide (MSP430BT5190_CC2560_Developers_Guide)

but the SDK (MindTree) not provide db_gen.c

My Demo firmware : MSP430BT5190-CC2560 SDK (MSPEXP-PAN13XX-SDK-GA: MSP430F5438 EXP Board + PAN13xx Bluetooth SDK GA 1.0)

Has the method to solve?

thanks.

Dunk Wu,

You are right. It says that it is implemented in db_gen.c and db_gen.h. db_gen.c is not provided in source but you don't need it since all DEFINITIONS are listed under dg_gen.h. In summary, you just need to modify db_gen.h which is provided in source.

I hope it is clear now. Please let us know.

Hi Miguel ,

i want change Service Name(BlueMSP430), but db_gen.h has not provided the revision program.

ex : /* Attribute value array */

const UCHAR value_arr[] = {

0x0A, 0x00, 0x00, 0x00, 0x00, ...........

/* ServiceName */

0x25, 0x0B, 0x42, 0x6C, 0x75, 0x65, 0x4D, 0x53, 0x50, 0x34, 0x33, 0x30, 0x00 };

I guess db_gen.c in libspp_core.r43.

Therefore, can not i solve this problem !?

thanks.

Dunk,

I apologize I made a mistake in my previous post. Both files, db_gen.c and db_gen.h are provided as source in the SDK (I just double checked). You should modify the Service Name defined in the const UCHAR value_arr[] array in the db_gen.c.

C:\Texas Instruments\MSPEXP-PAN13xx SDK\GA 1.0\MSP430-CC2560_Applications\Source\bluetooth\export\common_appl\db_gen.c

C:\Texas Instruments\MSPEXP-PAN13xx SDK\GA 1.0\MSP430-CC2560_Applications\Source\bluetooth\export\common_appl\db_gen.h

Dunk,

If you look at the array :

0x25, 0x0B, 0x42, 0x6C, 0x75, 0x65, 0x4D, 0x53, 0x50, 0x34, 0x33, 0x30, 0x00 };

You'll see the name:

0x25:0x0B:0x42:0x6C:0x75:0x65:0x4D:0x53:0x50:0x34:0x33:0x30:0x00

?%???B?l?u?e?M?S?P?4?3?0??

For example, 0x42 is the letter B in Ascii.

Regards,

Gustavo

Hi Miguel,

I revise the Service Name to succeed.

I checked "MSPEXP-PAN13xx SDK" file, it is provide db_gen.c.

Therefore, i try a way.

From "MSPEXP-PAN13xx SDK" In the file, copy "db_gen.c" to "MSP430BT5190-CC2560 SDK" In file.

"db_gen.c" add in project, then "built all" is pass.

then i checked Service Name which already to change.

This method is feasible.

thanks.

Hi Gustavo,

I understand.

thanks.
