Substantial information is returned in the message. The last two byes of the message give the ADC reading in Little-
Endian format, 7B 08. The ADC reading is thus 0x087B (2171). The RSSI value is the byte following the address, 0xB7 (-
73 dBm). The
TxStatus
byte to the right of the
GetRemoteRegisterReply
Packet Type is 0x00, showing the packet was
acknowledged on the RF channel.
7.5.4 Event Message
The configuration example shown in Section 7.5.2 above causes the remote with MAC address 0x123456 to start sending
event messages every 10 seconds as shown in the log below:
FB 12 28 56 34 12 B8 00 7A 01 36 01 FF 01 10 00 20 01 40 01

RxEvent
messages are
PktType
0x28. The message payload consists of the states of GPIO0 through GPIO5, the input
voltages measured by ADC0 through ADC2, the event trigger(s), and the DAC output settings. Note the ADC readings,
event flags and DAC settings are presented in Little-Endian order. The remote is assumed to be always ON in this exam-
ple. If the remote is placed in periodic sleep mode (
SleepMode
= 1), a suitable value of the
WakeResponseTime
parame-
ter should be set to allow the base application to analyze the I/O report and send back a command to the remote as
needed.
