LAN function issue #253

Closed hetvishah08 closed 5 years ago

hetvishah08 commented 5 years ago

I am developing an application with ESP32 DevkitC and LAN8720 where using ModbusTCP i am trying to read the holding registers.I want to connect whenever needed and then disconnected it.I am facing an issue here when i use:

Code:

from machine import Pin from machine import UART from time import sleep import network from uModBusTCP import uModBusTCP as TCP

def lan_config():

l = network.LAN() l.init(mdc = Pin(23), mdio = Pin(18), power = Pin(17), phy_type = network.PHY_LAN8720, phy_addr=1) l.ifconfig() l.active(1) m = l.ifconfig() print(m)

while True: lan_config() modbus=TCP('192.168.29.53', 502, 60) print(modbus.read_holding_registers(1, 0, 2,True)) print(modbus.write_single_register(1, 4, 101, True)) print('hello') modbus.close() l.deinit() sleep(5)

I get debug messages as following:

When I changed my code to this it works fine but then i cannot shut the LAN:

from machine import Pin from machine import UART from time import sleep import network from uModBusTCP import uModBusTCP as TCP

def lan_config():

l = network.LAN(mdc = Pin(23), mdio = Pin(18), power = Pin(17), phy_type = network.PHY_LAN8720, phy_addr=1) l.ifconfig() l.active(1) m = l.ifconfig() print(m)

while True: lan_config() modbus=TCP('192.168.29.53', 502, 60) print(modbus.read_holding_registers(1, 0, 2,True)) print(modbus.write_single_register(1, 4, 101, True)) print('hello') modbus.close() sleep(5)

Debug Messages: After every 5 seconds

Also after reset my code hangs at LAN settings:

After this the code doesn't run and is stuck here.
