Mesh Network

A typical network setup:

Quick Start Instructions

To demonstrate Mesh with three modules, use the following procedure:

1. Use 0001 node as the on/off switch (client).
2. Use 0003 node as the target (server).
3. Use 0002 node as the relay.
4. Be sure the three encryption keys are set properly. Use the AT command SetKeyPass.
5. at+ab SetKeyPass dev [Device]
6. at+ab SetKeyPass app [Application]
7. at+ab SetKeyPass net [Network]
8. Use distance to separate 0001 and 0003 so that they cannot communicate directly. Alternatively, use the AT Block command to block messages between 0001 and 0003.
9. at+ab Block [local BD Address]
10. The RSSI command can be used to test and determine the strength of the received Mesh messages.
11. Use the AT OnOff command on 0001 to send an On or Off command to 0003. Once the on/off msg is received, 0003 will respond by sending its status to 0001.
12. Since 0001 and 0003 is either too far or have its messages blocked from each other, these messages should be relayed through 0002.

General setup

• Serial COM port settings: 115200/N/8/1
• All AT commands must terminate with a CRLF.
• AT commands may be sent over the BLE link or the COM port/module UART.
• Commands are non-case sensitive, except device names and passwords/passcodes.
• Command parameters use ASCII format, unless stated in ASCII hex format. ASCII hex uses 2 characters per hex byte.

Examples

1. Be sure to use a build version of at least 240411A Mesh.
2. Set all node addresses. See config var92.
3. Set the key passwords using the SetKeyPass AT command.
4. For testing, use the block AT command.
5. The following are the example config settings for Nodes 0001, 0002, and 0003.
