CC2642R: [simple_peripheral example] cannot enable L2CAP Connection Oriented Channels and PTM at the same time

Part Number: CC2642R

Tool/software:

Hi,

There is a compile error when I enable both PTM and L2cap CoC for simple_peripheral example. (sdk version: sdk_7_10_01_24)

Could you help with this issue? Thank you!

    Hi,

    Thank you for reaching out. Can you share how you are enabling PTM and L2CAP on your project?

    Best Regards,

    Hi Jan,

    The steps to reproduce this issue are as follows：

    1. import ccs project C:\ti\simplelink_cc13xx_cc26xx_sdk_7_10_01_24\examples\rtos\CC26X2R1_LAUNCHXL\ble5stack\simple_peripheral

    2. enable "BLE->BLE Features-> L2CAP Connection Oriented Channels" and "BLE->Advanced Settings->PTM" in simple_peripheral.syscfg

    3. rebuild

    Hi,

    Got it. i was able to reproduce the issue. It seems the behavior only occurs if both PTM and L2CAP are enabled. I believe the problematic line is line 714 in icall_hci_tl.c

    Can you try moving line 714 outside of the #ifdef? You can do this without modifying your SDK installation, by deleting the linked file for icall_hci_tl.c found in iCallBLE and replacing it with a local copy (by dragging and dropping the SDK copy to the iCallBLE folder in CCS and clicking on copy).

    Best Regards,

    Jan
