6.8 Application Examples

Operation using ZentriOS

Each AMW007 module is pre-installed with and li-

censed to use ZentriOS-WL, Zentri’s feature-rich and

reliable Wi-Fi networking application. The module can

be used with an external host microcontroller via the

serial interface command API.

For more details see https://docs.zentri.com/zentrios.

To use ZentriOS with a host processor, the module only

requires an external connection to power and a UART

serial interface. A host processor connects to the UART

(pins 7/8) as shown in Figure 12. Zentri recommends

UART hardware flow control (RTS/CTS) is used to im-

prove the reliability of data communications.

GPIO0 is the default factory reset pin. In order for the

module to boot normally (and avoid factory reset), the

GPIO0 pin must be pulled or driven to ground during a

reset. A 100k pull down resistor on this pin is recom-

mended.

The CHIP_EN pin must be pulled to 3V3 to enable ZentriOS

to boot. A 100k pull up resistor is recommended if this pin

is not driven by an external host MCU.

The WAKE pin is an output from the module, and may be

used to wake the module from deep sleep. Connect WAKE

to RESET_N using a 1k resistor to enable sleep/wake func-

tionality. This connection is not required if sleep/wake

functionality is not used, or a host MCU has explicit control

of the RESET_N pin.

Hardware Design Guidelines

For hardware design guidelines, see:

Zentri online documentation, AMWx06 Hardware Design

The general guidelines for the AMWx06 devices apply to

all Zentri devices.

Pin numbers should be adjusted for actual device used.
