6.5 Application Examples

UART Application for Configuration and Streaming

Follow the schematic in Figure 6 to connect a host MCU UART to the User UART serial interface of the AMS00x mod-

ule. This application enables a host MCU to configure the module using command mode, and transfer data back and

forth to a remote device via the Bluetooth LE wireless interface using stream mode. UART hardware flow control is

not required, but is recommended for streaming continuous data.

Note: The 10K pullup resistor on pin 6 allows the module to go to sleep and stay asleep. It also enables sleep current

to be reduced to a typical value of 1.65uA. If pin 6 is not driven high the wake-up circuit may be highly sensitive to

small variations in capacitance or voltage on module pins. Module sleep current may also remain higher, at around

200uA.

6.6 Operation using TruConnect

The information in this section provides a very brief

overview of basic operation using TruConnect. For de-

tailed information, consult the TruConnect Reference

Guide available online at http://truconnect.ack.me

Bootup Configuration

At boot up, TruConnect attempts to load saved configu-

ration settings i.e. the saved state of TruConnect varia-

bles. There are three configuration sets that may be

loaded, depending on the state of the module. User

settings may be saved/changed as required, Factory

Settings may be saved only once, and Default settings

are hardcoded into the app at compile time and cannot

be changed. Configuration load at boot time occurs in

the following sequence:

1. User Settings. This configuration is set by a user and

any supplied arguments. User configuration can be

changed at any time, and the configuration is delet-

ed when a factory reset is performed. If no user

configuration is present or it is corrupted then

TruConnect attempts to load the factory settings.
