This class controls Ethernet NIC devices of CH395
.
Currently, only EC600N module series support this feature.
ethernet.CH395
class ethernet.CH395(mac, ip='', subnet='', gateway='', spi_port=-1, spi_cs_pin=-1, extint_pin=-1, reset_pin=-1, work_mode=0)
Loads CH395 driver, initializes CH395 Ethernet NIC and returns CH395 NIC object.
Parameter:
mac
- Byte stream. MAC address with a length of 6 bytes.ip
- IP address of Ethernet NIC. The default value is an empty string'', indicating that the default IP address is 192.168.1.100
in the program.subnet
- Subnet mask address of Ethernet NIC. The default value is an empty string'', indicating that 255.255.255.0
is used as the subnet mask.gateway
- Gateway address of Ethernet NIC. The default value is an empty string'', indicating that the last bit of IP address is replaced with 1
as the gateway address.spi_port
- Connect to SPI port of CH395
. The default value is -1
, indicating that the last configured value is used and the default configuration in the program is SPI1
port.spi_cs_pin
- Connect to SPI
chip select GPIO pin of CH395
. The default value is -1
, indicating that the last configured value is used and the default configuration in the program is Pin.GPIO4
.extint_pin
- Connect to external interrupt GPIO pin of CH395
. The default value is -1
, indicating that the last configured value is used and the default configuration in the program is Pin.GPIO24
.reset_pin
- Connect to reset GPIO pin of CH395
. It indicates that the last configured value is used and the default configuration in the program is Pin.GPIO30
.work_mode
- Configure Ethernet working mode. The default mode is terminal mode. 0
and 1
respectively represents terminal mode and gateway mode. Terminal mode indicates that the module is used as a terminal device to connect to a network supply device to access the network. Gateway mode indicates that the module is used as a gateway to provide network access for external devices through LTE network.CH395.set_addr
nic.set_addr(ip, subnet, gateway)
Configures NIC static IP Address.
Parameter:
ip
- IP address of Ethernet NIC. The value is an empty string'', indicating that the default IP address is 192.168.1.100
in the program.subnet
- Subnet mask address of Ethernet NIC. The value is an empty string'', indicating that 255.255.255.0
is used as the subnet mask.gateway
- Gateway address of Ethernet NIC. The value is an empty string'', indicating that the last bit of IP address is replaced with 1
as the gateway address.Return Value:
0 - Successful execution
Other values - Failed execution
nic.set_addr('192.168.1.100', '', '')
CH395.set_dns
nic.set_dns(primary_dns, secondary_dns)
Configures NIC DNS server.
Parameter:
primary_dns
- Primary address of DNS
server.secondary_dns
- Secondary address of DNS
server.Return Value:
0 - Successful execution
Other values - Failed execution
Example:
nic.set_dns('8.8.8.8', '114.114.114.114')
CH395.set_up
nic.set_up()
Enables NIC and then NIC processes network interfaces and messages normally.
CH395.set_down
nic.set_down()
Disables NIC and then NIC no longer processes network interfaces and messages.
CH395.dhcp
nic.dhcp()
Obtains dynamic IP. This method is used in the terminal mode so that IP information can be automatically obtained.
Return Value:
0 - Successful execution
Other values - Failed execution
CH395.ipconfig
nic.ipconfig()
Obtains NIC network information. MAC address, host name, IP address type, IP address, subnet mask, gateway address and DNS server address can be obtained through this method.
Return Value:
Returns list type.
The format is as follows:
[(mac, hostname), (iptype, ip, subnet, gateway, primary_dns,secondary_dns)].
Parameter | Type | Description |
---|---|---|
mac |
str |
mac address and the format is'XX-XX-XX-XX-XX-XX' . |
hostname |
str |
NIC name |
iptype |
str |
ip type. 4 indicates IPv4 and 6 indicates IPv6 . Currently, only IPv4 is supported. |
ip |
str |
IP address |
subnet |
str |
Subnet mask |
gateway |
str |
Gateway address |
primary_dns |
str |
Primary address of DNS server |
secondary_dns |
str |
Secondary address of DNS server |
CH395.set_default_NIC
nic.set_default_NIC(ip)
Configures the default NIC.
Parameter:
ip
- Default NIC IP address.Return Value:
0 - Successful execution
Other values - Failed execution
Example:
nic.set_default_NIC('192.168.1.100')
CH395.status
nic.status()
Obtains NIC current status.
Return Value:
Tuple type.
The format is as follows:
(dev, active, link).
Parameter | Type | Description |
---|---|---|
dev |
bool |
Whether NIC device is normally connected. True and False respectively indicate that NIC device is connected and is not connected. |
active |
bool |
Whether NIC is activated. True and False respectively indicate enable and disable, which correspond to set_up and set_down . |
link |
bool |
Whether the network cable of NIC is connected. True and False respectively indicate the network cable is connected and is not connected. |
