[WICED-SDK-2.2.1]

We are attempting to connect with a router through WPS without having to modify the DCT, and thus are using the low-level wiced_wifi_join().

Our code uses wiced_wps_enrollee() to find APs and wiced_wifi_join() to join them.

join() returns WICED_SUCCESS, and wiced_network_is_up(WICED_STA_INTERFACE) returns TRUE immediately after joining.

Subsequent code that attempts to use this interface, however, fails at the link check stage.

For example, wiced_udp_create_socket() returns -4 (WICED_NOTUP).

When we instead hardcode this access points credentials and use wiced_network_up(), we do not run into any issues.

What steps do we need to take before/after wiced_wifi_join() to bring up our connection?

WiConnect sits on top of WICED to enable a faster time to market through an easy to use API.

WiConnect runs as standard on all ACKme Networks Wi-Fi modules

HTTP Post Example

The following (fictitious) HTTP post example shows how to post data to an HTTP web server using the WiConnect HTTP API. The HTTP body data posted in this example is a small piece of JSON (sent using stream_write 0 7). Since the -o option is used with the

http_post command, a connection stream to the HTTP server is opened, but the HTTP post is queued locally on the module.

Queuing the HTTP post locally provides the ability to add HTTP headers using the

http_add_header command, and to post data in the HTTP body using the stream_write command. Once all headers and body data are queued, the HTTP post is sent to the server and completed using the http_read command.

Any response data received from the server may be read using stream_read.

Couple of emails came in recently asking if Eagle CAD files are available for the AMW004 'Wallaby' module by ACKme.

The Answer - yes!

Hi,

   I'm not very satisfied with the antenna provided on the module, how can I choose other kind of antenna? What specs should I look at? Thanks.

  Best regards.

I solved the problem with toolchain but now i get other, my Olimex Tiny H is not seen by Eclipse

after build Eclipse try  to download Code to my IC but iget the massage:

Downloading Bootloader ...

Everything is connected correctly, no Debugger running, settings seems to be right.

Now  i don't know what to do.

Here’s another useful teach-in that will help you get to market faster …

WiConnect is a simple to use front end to WICED and by using WiConnect many of the simple tasks you are looking to achieve come about much quicker allowing you to focus on your application rather than the network or wireless portion. This teach in shows the basis of a simple streaming serial interface.

Stream Mode

As depicted in the following diagram, stream mode provides a transparent connection between a serial port and a network stream. It is perfect for implementing applications such as a wireless serial port.

Stream mode is used primarily by host applications that can handle asynchronous data (with the optional use of hardware flow control). It is perfectly suited to applications that only need to use a single network stream at any one time.

Configuration

The simplest way to setup an ACKme module to use Stream mode is to do all the WiConnect configuration first using command mode, then reboot into stream mode.

Configuration involves just a few simple steps:

• Setup a wireless and network interface to use with stream mode e.g. wlan interface and TCP client. This typically requires setting up the wireless interface and network stream to auto-connect, or enable connection using a GPIO control pin.

• Set the serial bus.mode to stream.

• Then save and reboot the module.

Both the wlan and softap interfaces have an auto-start on bootup capability using the wlan.auto_join.enabled and softap.auto_start variables. The TCP server has auto-start capability using the tcp_server.auto_start variable. Network clients can be started using a GPIO or manually by breaking out of stream mode as described below.

Breaking out of Stream Mode

When the serial bus is in Stream mode, commands are disabled and every character sent to the serial port is automatically forwarded to a network stream. There are two ways to break out of stream mode and enable command mode entry temporarily. The first method uses a character sequence configurable with the bus.stream.cmd_seq. By default, the stream break out sequence is $$$. The other option available to break out of stream mode is to use a GPIO configurable with the bus.stream.cmd_gpio variable. When you're done entering commands, return to stream mode by simply issuing the exit command.
