Table 2 shows an overview of the availablecommands when the module is in configuration mode. The details for each command is found in Appendix A .Table 2 – Configuration Commands overviewCommandParameterRC12xxRC11xxRC25xxRC17xxStored in NVM(Flash)Stored in RAMASCII hex‘C’ 0x43 Channel ✔ ✔ ✔ ✔ ✘ ✔‘M’ 0x4D Memory configuration ✔ ✔ ✔ ✔ ✔ ✘‘P’ 0x50 Output power ✔ ✔ ✔ ✔ ✘ ✔‘S’ 0x53 Signal Strength (RSSI) ✔ ✔ ✔ ✔ ✘ ✔‘T’ 0x54 Destination address ✔ ✔ ✔ ✔ ✘ ✔‘U’ 0x55 Temperature monitoring ✔ ✔ ✔ ✔ ✘ ✔‘V’ 0x56 Voltage monitoring ✔ ✔ ✔ ✔ ✘ ✔‘X’ 0x58 Exit command ✔ ✔ ✔ ✔ ✘ ✔‘Y’ 0x59 Memory Read one byte ✔ ✔ ✔ ✔ ✘ ✔‘Z’ 0x5A Sleep mode ✔ ✔ ✔ ✔ ✘ ✔‘0’ 0x30 List Configuration Memory ✔ ✔ ✔ ✔ ✘ ✔‘1’ 0x31 Test mode 1 ✔ ✔ ✔ ✔ ✘ ✔‘2’ 0x32 Test mode 2 ✔ ✔ ✔ ✔ ✘ ✔‘3’ 0x33 Test mode 3 ✔ ✔ ✔ ✔ ✘ ✔‘4’ 0x34 Test mode 4 ✔ ✔ ✔ ✔ ✘ ✔‘@RC’ 0x40 0x52 0x43 Reset Configuration to factory defaults ✘ ✔ ✔ ✔ ✔ ✘‘@RR’ 0x40 0x52 0x52 Reset Radio ✘ ✔ ✔ ✔ ✘ ✔2.3 UART Interface – Send and receive messagesThe module acts as a buffered packet radio, hence all data to be sent is stored in the module before they aretransmitted by the RF circuitry. It is possible to configure different send criterias for the data stream:• PACKET_LENGTH will initiate the radio to send when the specified number of bytes are received.• PACKET_END_CHARACTER will initiate the radio to send when end character is received.• PACKET_TIMEOUT will initiate the radio to send the received data after a given timeout. The timeout isstarted when the first byte is recieved on RXD.Likewise, when data is received they are stored in the module before they are sent to the host. This allows thecommunication controller to add address information, CRC and encryption during transmission, and to do errorcheck and decryption of the received data.The RC232™ protocol has a built in error detection based on a 16 bit CRC. The error detection can be enabledwith CRC_MODE in the configuration memory. If a received packet contains an invalid checksum, it will bediscarded and not sent to the host. |
