Working on raspberry with Arduino connected over USB. Communicating over python with minimalmodbus library Trying to make reconnection when Arduino was unplugged for a while.
I tried to repeat the connection code again on error, didn't helped.
Is there any function to reconnect on the serial connection lost?
minimalmodbus.baudrate = 9600
instr = minimalmodbus.Instrument('COM5', 1)
instr.serial.baudrate=9600
instr.debug=False
You may be facing this problem because you are not closing the COM port. Therefore, you can try first closing that by using below command:
instrument.close_port_after_each_call= True
Your code should look like this:
minimalmodbus.baudrate = 9600
instr = minimalmodbus.Instrument('COM5', 1)
instr.serial.baudrate=9600
instr.debug=False
instr.close_port_after_each_call= True
except:
print('please check your connection')
