1. Compile the WiFi related function as module, generate Bcmdhd.ko, the module information of Bcmdhd.ko, this module depends on Cfg80211.ko and Rfkill.ko.2. Write the script, boot automatically load WiFi module.3. Use the command
At first I was connecting a WiFi module to my Arduino uno, but Uno has only one UART and this UART is connected to the USB port. There have been some and very strange problems. After entering the setup mode (M0=1, m1=1), it is indeed possible to set the parameters of the settings are saved successfully, but using C3C3C3 can not get to the version without any return, may be my RX data line without contact is
Due to project work requirements, point-to-point and multi-point transmission of wifi must be implemented on the embedded E9 platform.
WiFi module chip: Reiling 3070 Chip
Embedded platform: E9 (ARM)
Cross-compilation environment: Arm-None-Linux-gnueabi
1. First download the driver for the Wi-Fi module
2. Cross-compi

In the past SCM programming process, probably most people are more familiar with the MCU WiFi module and the server to establish a socket connection. However, it may be a better option to establish an HTTP connection when we are confronted with the fact that our data requires a dynamic display of the Web page, a file upload, and so on, when the two parties do not need to stay connected online.

Huawei mw269v2 is a Wi-Fi + bt + FM three-in-one module, and WiFi uses Broadcom bcm4330,Sdio interface. The kernel version of the android 4.0.3 BSP on s5pv210 is 3.0.8. power on the Development Board through USB port, and insert the TF card interface through the adapter board. Print the following information: mmc_attach_sdio entermmc_attach_sdio mmc_attach_busmmc2: Card claims to support voltages below the
connection process.
The following describes the debugging methods. We know that the SD card driver under wince is mainly composed of three parts: bus driver, host controller driver and client drivers. Shows the relationship between the three and applications and the operating system.
We can see that the bus driver is an abstract management layer between the client driver and the host controller driver. It provides a standard API for the client driver to run on different wince systems.
