L2CAP is the underlying technology powering GATT. BLE 5 exposes L2CAP COC (Connection Oriented Channels) allowing a streaming API that leads to much higher throughputs than you can achieve with updating GATT characteristics. The patch follows the established infrastructure very closely. The main components are: - `NimBLEL2CAPChannel`, encapsulating an L2CAP COC. - `NimBLEL2CAPServer`, encapsulating the L2CAP service. - `Examples/L2CAP`, containing a client and a server application. Apart from these, only minor adjustments to the existing code was necessary.
