The application layer is the layer that uses the services provided by the stack to perform a specific task. In this case, for demonstrating functionality, the user layer waits for the ASCII character 't'. After the character has been received, the MSP430 obtains a temperature reading from the ADC module integrated temperature sensor and appends it through the use of the IrCOMM layer to the user data field of a data carrying IrLMP frame. The temperature sent then is displayed by the peer device, and the MSP430 then issues more credit to the peer entity so that more data can be sent.
