10.2. S2W and STW Mode Selection

Serial-Through-WiFi is a feature realized by combining Command Mode and Through Mode operations.

Command Mode supports all the Serial Interface commands described in the prior sections of the

document.

In particular, the STW provisioning commands are used to configure the connectivity parameters for the

module, including the WiFi and TCP/IP configurations. Those parameters are used in the Through Mode

to establish TCP connections over WiFi with a peer to enable serial data to flow transparently between

the UART interface of the module and the target.

The module determines the particular Mode of operation by sampling GPIO1 at power up. GPIO2 is

used in Through Mode to indicate the connection state between the module and its peer. A block

diagram of the hardware interface is shown below.

GPIO1 Usage

High S2W(Command mode) mode

Down STW(Through Mode) Mode

10.3. Boot mode selection

Default pin setting is applied as below,

-BOOT1 is don’t care

-BOOT0 is 10k ohm pull down

because software embedded module is supplied.

Also pin setting are available for other purpose as below.

11. Packing

11.1. Tray

The module is placed in a pocket of the above tray with following rules.

- The module’s metal shield contacts a tray’ indentation

- Its chip antenna on the module is directing to an arrow on a tray.

11.2. Packing in a inner box

11.3. Shipping box

- Please keep any packaging below 40 deg.C until using it up, because a tray is potentially deformed

with storage over the temperature.

- Please don’t stack the shipping box over 1.5m height to avoid any physical problem.

- Four inner boxes is general number in a shipping box, but it may be dummy for some of inner boxes.

- One inner box has 420pcs as standard q’ty.

- MOQ is 1680pcs, which are constructed four inner boxes.
