Description
RF1212 is a low-cost sub-1 GHz transceiver module designed for operations in
the unlicensed ISM (Industrial Scientific Medical) and LPRD bands. FSK
(Frequency Shift Keying) modulation/demodulation, multi-channel operation, high
bandwidth efficiency and anti-blocking performance make RF1212 modules easy to
realize the robust and reliable wireless link.
The module can be configured to work in different channels with 200 KHz
space. It adopts high efficient looped interleaving EDAC (Error Detection and
correction) coding with coding gain up to 3dB which keeps in advance in error
correction and coding efficiency over normal FEC (Forward Error Correction)

1. Data Packet Pattern
PREAMBLE SYNCWORD ID (Optional) DATA + FEC +CRC
Table 4 RF1212 Packet Pattern
The preamble is alternative “1010” codes which is used to make the clock of receiver
synchronous with transmitter. In normal conditions, 32 bits preamble is enough for
use. When RF1212 works in power-saving mode, the preamble also can be functioned
to wake up the receiver and it must be long enough in order to obtain such a function.
If the receiver is configured to wake up at the interval of one second, it wakes up and
searches the preamble (TW) every other second and lasting 16 bits. The transmitter
must transmit preamble longer than 1 second and then send synchronous word, which
means the receiver can detect the preamble and wake up receiver successfully.
2. Working Mode
RF1212 can work in 4 different modes which can be configured through SETA and
