摘要： A method is provided for wireless communication between a wireless remote control device comprising a peripheral device and a controller on a materials handling vehicle comprising a central device. The method may comprise: polling via a plurality of connection event requests, by the central device, communicated with the peripheral device with which the central device is paired, the peripheral device comprising one or more activatable switches. Based on the status of one or more activatable switches, the peripheral device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one communication operating mode of the peripheral device, wherein each reply message is indicative of the status of the one or more activatable switches. Calculating, by the central device, a number of missed messages.

摘要： A method is provided for Bluetooth Low Energy (BLE) communication between a remote control device comprising a peripheral BLE device and a controller on a materials handling vehicle comprising a central BLE device. The method comprises: polling via a plurality of connection requests, by the central BLE device, communicated with the peripheral BLE device with which the central BLE device is paired. The peripheral BLE device comprising one or more activatable switches. Based on the status of the one or more activatable switches, the peripheral BLE device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one of a first or a second communication operating mode. When operating in the first communication operating mode, the peripheral BLE device replies to only a portion of the plurality of connection requests, wherein each reply message is indicative of the status of the one or more activatable switches.
