One 、 Drive migration

Two 、 Application testing

1、 modify test_config.h Configuration parameters in .

The main parameters to be modified are as follows

2、 And then in c_support Run... In folder make command To compile the .

3、 Enter the relevant test command

sudo ./test.out [scan] [sta_connect] [sta_disconnect] [ap_start] [ap_vendor_ie] [sta_list] [ap_stop] [wifi_tx_power] [ota <Esp_binary_path>]

note：
1、 The commands in brackets are optional , You can only enter one or more combinations . See the source code for specific implementation

2、sta_connect after , User needs to run DHCP The client is from the outside AP obtain IP Address . 

sudo dhclient ethsta0 -r

sudo dhclient ethsta0 -v

Command line argument	Operation
sta_connect	take ESP32 The station is connected to the outside AP, take ESP32 Of MAC The address is assigned to ethsta0
sta_disconnect	To break off ESP32 With the outside AP And down ethsta0 Interface
ap_start	start-up ESP32 softAP, take ESP32 softAP Of MAC The address is assigned to ethap0
ap_stop	stop it ESP32 softAP and down ethap0 Interface
scan	Scan external access points
sta_list	List connections to softAP External sites
ap_vendor_ie	Set vendor information element for ESP32 softAP by ESP32 softAP Set supplier information elements
wifi_tx_power	Set up WiFi Maximum transmit power and obtain WiFi Current transmit power
ota </path/to/ota_image.bin>	Use local OTA Binary execution OTA operation

3、 ... and 、 Test code sorting

1、 Test the organizational structure of the code ：

CC = gcc

CROSS_COMPILE :=

CFLAGS = -C -Wall 

DIR_HOST_COMMON = $(PWD)/../../../host_common
DIR_COMMON = $(PWD)/../../../../common/

INCLUDE += -I$(DIR_HOST_COMMON)/include/
INCLUDE += -I$(DIR_COMMON)/protobuf-c/
INCLUDE += -I$(DIR_COMMON)/include/

SRC += $(DIR_COMMON)/protobuf-c/protobuf-c/protobuf-c.c
SRC += $(PWD)/platform_wrapper.c
SRC += $(DIR_COMMON)/esp_hosted_config.pb-c.c
SRC += $(DIR_HOST_COMMON)/transport_pserial.c
SRC += $(DIR_HOST_COMMON)/commands.c test_api.c

PWD := $(shell pwd)

all: test

test:
	$(CROSS_COMPILE)$(CC) $(CFLAGS) $(INCLUDE) $(SRC) $(@).c -o $(@).out

stress:
	$(CROSS_COMPILE)$(CC) $(CFLAGS) $(INCLUDE) $(SRC) $(@).c -o $(@).out

clean:
	rm -f *.out *.o

2、 Call framework

test.c   ---->  test_api.c  ----->   command.c

explain ：

1、test.c It is mainly based on the commands entered by the user , Call different test logic , Such as int test_station_mode_connect(), The test logic is implemented in test_api.c To realize

2、test_api.c Will call command.c And ESP32 Interact .command.c See the following website for the function description of ：

3、 Code flow

1、 Test whether the data path is normal

const char* transport = "/dev/esps0";
esp_hosted_driver_handle.file_desc = open(transport,O_NONBLOCK|O_RDWR);// Turn on the device 
buf = (uint8_t *)esp_hosted_calloc(1, DUMMY_READ_BUF_LEN);
count = read(esp_hosted_driver_handle.file_desc,(buf), (DUMMY_READ_BUF_LEN));// Reading data 
.......
esp_hosted_free(buf);// Release buffer
ret = close(esp_hosted_driver_handle.file_desc);// Turn off the device
