Hi Roger,

Sorry for the delay.

The LE L2CAP CoC is not supported for OTA updates with TI OAD. The primary method for sending data from the OAD target to the OAD distributor is GATT notifications. TI OAD are designed to work with GATT characteristics for data transfer efficiency and validation during the updates. Implementing the OTA updates directly with L2CAP CoC might need more development effort compared to using OAD.

You can read more information regarding the L2CAP CoC here and the OAD here.
