CHAPTER 11 Connection Protocols

---

CLDC Connections

The CLDC provides a generic connection API which allows a mobile device to connect to a wide variety of network and communications ports. The CLDC does not, however, specify what these connection protocols are. It leaves that up to profile specifications, as well as device manufacturers.

The MIDP 1.0 specification mandates that all devices must support at least the HTTP 1.1 protocol. Many device manufacturers have also included other protocols in their MIDP implementations.

In order to support the largest possible set of devices, Simplicity for Palm OS Platform includes a large set of protocols. All MIDP 1.0 devices will support the http protocol, and may also support other protocols. When selecting protocols, it is wise to confirm that the intended deployment device has support for a particular protocol. (Conversely, one often selects a particular device, because it has support for the required protocol.)
