Starting a network with Telegesis Terminal

This is quick guide to starting a network using a few Telegesis ETRX2 or ETRX357 modules connected to the serial port of a PC or laptop and our Telegesis Terminal application program (downloadable from this website). For the sake of brevity we do not describe all the possible situations that can arise, but we have included a few redundant steps in this guide to smooth your path; for example, the AT+N and AT+PANSCAN commands are not always necessary, but they help you to discover how your devices are set up.

1. Have the appropriate manuals available for reference, for example the ETRX2 or ETRX357 Development Kit Product Manual and the R3xx AT Command Manual. The precise manuals that you will need may vary according to your devices and firmware.
2. Install Telegesis Terminal on your computer following the advice in the Development Kit Product Manual
3. Start Telegesis Terminal and establish serial connection with one or more modules. You can have more than one Telegesis Terminal open at the same time. Verify that you are correctly connected with the ATI command 
4. Select the device you want to become the network coordinator. Check whether it is already in a PAN with the command AT+N If it is in a PAN, leave the network with the command AT+DASSL 
5. Establish a new PAN with the command AT+EN 
6. Select another node to join the PAN. If you want it to be a Sleepy End Device configure it with the command ATS0AE=1;password (for R3xx firmware)
7. Check whether it is already in a PAN with the command AT+N If it is in a PAN, leave the network with the command AT+DASSL 
8. (Optionally) find all the available networks with the command AT+PANSCAN 
9. Join the PAN with either the command AT+JN or AT+JPAN:<, where is the radio channel and the PAN ID as reported by AT+PANSCAN
10. Verify that the device has joined the network with the command AT+N 
11. Scan the network and create new Telegesis Terminal buttons by clicking on "Configure" Find the buttons labelled "Ident Node1" etcand check your network connections by clicking on each one.
12. Now you can try experimenting with broadcast and unicast messages, and reading and writing the S-registers to test the buttons and LEDs on your development kit boards.
