By default, the motes in starter kits are configured for master mode; a demo mode where the API is disabled and an application is run that generates sample data and controls joining. To use the mote alongside an external MCU, the mote has to be configured for slave mode mode (the default for LTC5800 chips and LTP59xx modules); the API is enabled and the mote expects a serially attached application to control it.
- Start by connecting the mote to your computer via the interface board, as shown in Figure 1.
- Identify the port name that maps to the CLI. For example, if you are in Windows and see the four COM ports pictured below, the CLI will be accessible through COM14.
- Connect to the mote CLI with a third-party serial terminal of your choice (e.g. putty). See Table 1 for configuration details.
Use the get mode command to see the current mode:
> get mode
master
Use the set mode command to switch to slave mode, followed by reset for the change to take effect. After rebooting, a new get mode should confirm the persistent mode change.
> set mode slave
> reset
> SmartMesh IP mote, ver 1.3.3.1 (0x100)
> get mode
slave
- Disconnect the mote from the interface board and make sure to remove its battery (if any), as we will power the mote from the MCU.
