BDE-SG1311P3 Sub-1G Wireless Module with PA

BDE-SG1311P3 Sub-1G Wireless Module with PA

Introduction

This user guide is for BDE-SG1311P3, a Wireless Module based on TI CC1311P3. It is a quick start guide for how to connect the module with the evaluation board BDE-EVB07, and how to build the first application. It also shows a demo for howBDE-SG1311P3receives a data packet that is sent from another BDE- SG1311P3.

Get Ready

The following tools are recommended to develop with BDE-SG1311P3.

Hardware tools

Two modules of BDE-SG1311P3(BDE-SG1311P3-BDETechnology Inc.(bdecomm.com))
PC or Laptop
Two Evaluation boards of BDE-EVB07 (BDE-EVB07-BDETechnologyInc.(bdecomm.com))
USB cable for power supply and debugging

Software tools:

Terminal software such as CCS, IAR.
CCS download
Software Development Kit (SDK)

Build Your First Application

Once have the Hardware and Software tools in place, please following the following steps.

Connect the Hardware

Connect the EVB07 to a PC or laptop using a USB cable. As shown in Figure 1, plugBDE-SG1311P3 with adapter board into the development board and connect all pins with jumper caps. Note that TXD and RXD need to be connected to DIO13 and DIO12withjumpers. Users can connect according to the mapping in Table 1.

Run an example/demo code

Step 1: For the first module, select a directory as workspace

Build Your First Application

Step 2: Find the option named “Import CCS project…”

Build Your First Application

Step 3: Click “Browse” and find the following path to import the project:
C:\ti\simplelink_cc13xx_cc26xx_sdk_6_10_00_29\examples\rtos\LP_CC1311P3\prop_rf\rfEchoTx\tirtos7\ccs

Build Your First Application

Step 4: Click the “Build” icon to build the project

Step 5: Click the “Debug” icon to download

Step 6: Click on this option to start debugging

Build Your First Application

By far you should have built your first application successfully. Now you should build your second application and download in another module to communicate between the two modules.

For another module, refer to Step 1 to find the discovered items according to the following path:
C:\ti\simplelink_cc13xx_cc26xx_sdk_6_10_00_29\examples\rtos\LP_CC1311P3\prop_rf\rfEchoRx\tirtos7\ccs

Follow steps 4 to 6 to complete the compilation and debug of the application.

You can see that the green LED and red LED in the first development board are flashing alternately, which indicates that the module is switching between TX and RX. The green LED means sending the data packet, and the red LED means not receiving the data packet from the other module.

Build Your First Application

The second module will not have any action on the two LEDs of the evaluation board when no packet is received. When a packet is received, the modules enables the red LED.
Then the second module switches from RX state to TX state and sends the data it just received.

When the first module receives the data packet from the second module, it compares the data packet with the previously sent data packet, and if the received data packet is the same as the previously sent data packet, it enables the green light.

When the two modules are in communication state, the first module only enables the green LED and the second module only enables the red LED.

Modifications regarding the use of PA

The default HIGH PA and SUB 1 GHZ pin mappings in demo are different from those of the BDE-SG1311P3 module. If HIGH PA is used, the user need to modify the setting of the antenna switch.

In the following tables, Table 2 is the truth table about antenna switch settings in demo and Table 3 is the truth table about antenna switch settings in BDE-SG1311P3 module.
The settings of HIGH PA and SUB 1 GHZ in the two truth tables are diametrically opposed.

If the default antenna switch setting is used, the actual transmitted power will be very low when PA function is turned on. To avoid this kind of situation, user can refer to the following code in the main program rewriting rf Driver Callback Antenna Switching() function. The prototype of the function is in ti drivers config. c.
