Configuring IEEE 802.15.4 modems 165 FIGURE 7.7 New function set successfully installed. determined by the SC parameter. SC is 16 bits long. Bit 0 represents channel 0xB and each higher bit represents the next channel through bit 15 that represents channel 0x1A. The default value of SC is 0x3FFF that causes channels 0xB through 0x18 to be scanned. The MY address for a ZigBee coordinator is set to zero and cannot be changed. The default DH value is zero that causes 16-bit addressing to be used. The default DL of 0xFFFF is the PAN broadcast address (packets are sent to every node). Drones may use modems configured as routers or end devices. Recall that only end devices are allowed to sleep. In most cases, battery-powered drones should be configured as end devices. As in the Series 1 case, non-PRO adapters are preferred if the coordinator or a router is within range. The default ZigBee router AT function set should be replaced with the ZigBee router API function set for drones to be configured as routers as shown in Figure 7.8. The PAN ID should be changed to match that of the coordinator. The MY address will be set to 0xFFFE until the router has joined a PAN and had an address assigned by the coordinator. Because the 16-bit addresses, known as network addresses in ZigBee networks, are assigned by the coordinator, there is no way to know beforehand what address will be assigned. As a result, 64-bit MAC addresses must be used, at least initially.
166 CHAPTER 7 Building an army of devices FIGURE 7.8 Configuring a Series 2 modem as a router. The first time a message is sent to a new node, a broadcast message is sent to discover the network address. If the destination has a route to the source, it replies with a unicast. If not, the destination performs a routing discovery before sending the reply. Either way, the network address is stored in a Network Address Table (NAT) on the source device to speed up future communications. Battery-powered drones can be configured as end devices in order to permit modems to go to sleep. The first thing that must be done is to upload the ZigBee end device API function set as shown in Figure 7.9. The PAN ID should be set to your selected value. The MY address and MP (parent) address will both be 0xFFFE until the device has joined a network. The default value for SC (scan channels) is 0xFFFF versus 0x3FFF for coordinators and routers. This scanning extra channels isn’t detrimental as the coordinator selects the channel, but changing it to match the coordinator and routers may speed up the joining process. REMOTE CONTROL THE EASY WAY In its simplest form, an XBee module can be used to replace a wired serial connection. A wired serial connection can be used to connect to a server via a TTY connection. By setting up TTY services on a port connected to an XBee radio on a drone, it
