1 Device Overview
1.1 Description
RF-SM-1077B1 Sub-1 GHz module is based on TI CC1310, which combines a flexible, very low-power RF transceiver
with a powerful 48 MHz ARM
®
Cortex
®
-M3 microcontroller supporting multiple physical layers and RF standards and a
dedicated radio controller Cortex
®
-M0 handling RF protocol commands that are stored in ROM or RAM. RF-SM-1077B1
integrates a 24.0 MHz crystal, a balun, a band pass filter, an antenna matching and an IPEX antenna matching which
make the module low cost, low power consumption and long wireless communication in Sub-1 GHz.
RF-SM-1077B1 is flashed transparent transmission firmware with AT commands by default. The default values are as
follows: 115200 baud rate, 8 data bit, no parity check bit,1 stop bit, 868 MHz operating frequency, 14 dBm TX power.
When the module starts to work, the serial port will print “Application Start\r\n”, and start transparent transmission mode
by default, serial port will transmit all the data except “+++”, please refer to the AT command in detail.
