Transceiver module TRX433-10C2 / TRX868-10C2 (Vers. 1.0E) 32 _____________________________________________________________________________________ Functional name READ hardware version Function 00H Functional call 0B0H, 00H, 03H Answer 00H, HVERS This is part of the module designation and is comprised of assembly variants and module type. The number 10 in TRX433-10C2 marks the hardware version 10. The transceiver is produced in multiple assembly variants. HVERS = 0AH: 16MHz µP clock frequency, internal voltage regulator 3.3V, loop filter 19.2kbaud HVERS = 0BH: 8MHz µP clock frequency, internal voltage regulator 3.0V, loop filter 19.2kbaud HVERS = 0CH: 16MHz µP clock frequency, without internal voltage regulator, loop filter 19.2kbaud HVERS = 0DH: 8MHz µP clock frequency, without internal voltage regulator, loop filter 19.2kbaud HVERS = 0EH: 8MHz µP clock frequency, internal voltage regulator 3.3V, loop filter 19.2kbaud There might accrue other hardware versions in future. See coding marking of the transceiver module. ________________________________________________________________________________ Functional name READ Frequency version Function 00H Functional call 0B0H, 00H, 04H Answer 00H, FVERS Frequency - version of the transceiver. This is part of the module designation. The Numbers 433 marks the frequency version in TRX433-10C2. FVERS = 0: 433 MHz band, 433.0625 - 434.7875MHz FVERS = 1: 868 MHz band, 868.0125 - 869.9875MHz FVERS = 2: 915 MHz band, 914.0125 - 915.9875MHz See coding marking of the transceiver module. _____________________________________________________________________________________ Functional name READ serial number Function 00H Functional call 0B0H, 00H, 05H Answer 00H, SER0, SER1, SER2, SER3 32bit unique serial number of the transceiver. SER0 = LSB, SER3 = MSB of the 32 bit-serial number See coding marking of the transceiver module. _____________________________________________________________________________________
Transceiver module TRX433-10C2 / TRX868-10C2 (Vers. 1.0E) 33 _____________________________________________________________________________________ Functional name READ RSSI current Function 01H Functional call 0B0H, 01H, 00H Answer 01H, RSSI RSSI in two’s complement, range -128 dBm … -60 dBm, resolution 1dBm Current RSSI value (Received Signal Strength Indicator) in dBm. The RSSI-value is established every 3ms independent of the functional call. RSSI shows therefore the field strength of a time that is max. 3ms back. RSSI = -128dBm while sending. The max. measurable value is -60dBm. The lower noise-floor depends mainly on the adjusted RF data rate. See paragraph RSSI and function READ RSSI peak. _____________________________________________________________________________________ Functional name READ RSSI peak Function 01H Functional call 0B0H, 01H, 01H Answer 01H, RSSI_peak RSSI_peak in two’s complement, range-128 dBm … -60 dBm, resolution 1dBm Maximum (peak hold) of the RSSI since last call. (Received Signal Strength Indicator) in dBm. The RSSI_peak is initialized after every call of this function and right after sleep. RSSI = -128 while sending. The max. measurable value is -60dBm. The lower noise-floor depends mainly on the adjusted RF data rate. See paragraph RSSI and function READ RSSI current. _____________________________________________________________________________________ Functional name READ temperature Function 01H Functional call 0B0H, 01H, 02H Answer 01H, TEMP TEMP in two’s complement, range -40°C … +115°C, resolution 1°C Temperature transceiver module in °C. The temperature is only actualized every 5 seconds no matter how often you invoke this function. The temperature is not actualized until the microcontroller was active for 5 seconds because all the timers are stopped during the sleep. The RF-part of the transceiver doesn’t have to be active to measure the temperature. _____________________________________________________________________________________
