1 Device Overview

1.1 Description

RF-SM-1077B2 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-1077B2

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-1077B2 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, 433 MHz operating frequency, 15 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.
