CC2650: Failing to send multi-byte data on characteristic 5 after reinstalling CCS7 and SDK (Toolchain)

Part Number: CC2650

Hello all,

I am using CC2650 Custom PCB based on Launchxl-CC2650 design.

BLE SDK 2_02_07_06

CCS7.4

Compiler TI Ver.5.2.6.

My code is based on "simple_peripheral_cc2650lp_app" example code.

Due to some reason I uninstalled CCS7, SIMPLELINK SDK and TI RTOS and reinstalled them all again.

Now, If I upload previous existing codes to my board by using this newly installed CCS and simplelink sdk and try to send data by writing to characteristic 5 from BLE central(Android App) my ble connections just connects and then disconnects again.

Please guide me about what are the possible reasons of this malfunctioning?

Hello Dnyaneshvar,

This is definitely a weird situation, what I would recommend first is to try and erasing previous bonds and rebonding. If the situation keeps occuring we would need to see over the air logs to understand the reason of the disconnection.

Kind Regards,

Hi,

I was using compiler version 5.2.4 for stack project and 5.2.6 version for App project.

After selecting compiler version 5.2.6 for stack project, only one time I successfully restored my previous code. It worked fine only once.

Now, when I try to upload the Stack project, I get error "no source available for 0x0000 something address"

Please help..

Hi Dnyanshvar,

Could you send a screenshot of the error, so I could better understand it (did it successfully build and fail to flash? or did it fail to build?). I would also try deleting and reimporting the base example your project is based on and adding your application code back in and see if you are still receiving build errors.

Kind Regards,

Rogelio

Hi RogelioD,

I am out of office today so won't be able to provide a screenashot.

The problem is with "Simple Ble peripheral Stack" project.

It builds successfully.

Problem comes when I try to flash it to my SoC.

Error is "no source available for 0x0000 something address"

Thank you

Hi Dnyaneshvar,

Your situation seems very similar to the following thread.

Best,

hi RogelioD,

I deleted the "Simple Ble peripheral Stack project".

Reimported it again to workspace, Now the problem of "no source available for 0x10003982" is solved.

But lets talk about original problem "Failing to send multi-byte data on characteristic 5".

I added "${PROJECT_LOC}\ICallBLE" inside project "Include options" #Include Search Path in Build settings.

After adding this I can send Multi-bye data, Complete Image is now being sent from BLE Master to my BLE peripheral device.

But When Image is sent 79% ble speed reduces suddenly and one packet takes about 1 sec to send from BLE master to BLE peripheral.

Is there any other Important #Include Search path I need to add?

Thank you

Hello All,

This problem is solved by reducing the "connection parameters" in simple_peripheral.c file.
