this code is breaking my sipy

this code is breaking my sipy

from machine import UART

uart=UART(1, baudrate=9600)

uart.init(9600, bits=8, parity=None, stop=1)
while(1):
print(uart.readall())

[iotmaker]

now i can only connect via wifi

[iotmaker]

the code is worky using putty and it does not work on the pymakr console...

so are we supposed to download programs vi the wifi and then run the serial port on putty or what?

@iotmaker
What do you mean it work on putty? To work with pymakr you need duplicate terminal.
What is your boot.py is it standard as:

from machine import UART
import os
uart = UART(0, 115200)
os.dupterm(uart)

If answer is yes, then your code only print all data from UART1 as output on UART0

yes thats what my code is doing. on the pymakr console i cannot see my prints. only on putty. ( i have putty closed when trying pymakr of course cant use the com port on two programs).

after the program is running i cant connnect to the sipy and download programs via serial port. Is that normal?

do i need to turn on the wireless everytime i want to download a program?.. .thanks

@iotmaker

what if you change it to

while(1):
    print(uart.readall())
    machine.idle()

I am not at home to try.

but i think you cannot use the COM port to download programs if you are using a program that uses the comport to print to the screen

i dont want to be switching my wifi connection every time i want to download something.

I do not understand your answer
But first, what are you trying to do? for what is your modification about uart1? You have some device on UART1? And UART/USB converter on UART0? Or what?

Secondly you can use AP+STA mode of wifi.

[iotmaker]

i just want to download and connect to the sipy via Serial or COM. but when i switch on the interface menu to use my COM port it cant connect. i dont like to connect to the sipy wifi everytime to download code.

@iotmaker
i still do not understand you
please back to previous post and look at my sample
do you have it in boot.py?

from machine import UART
import os
uart = UART(0, 115200)
os.dupterm(uart)

above duplicate rerminal on uart0 have you it in boot.py or not?

without duplicate terminal you can not work on COM throught Pymakr

Yes i have that code on the boot.py

[livius]

@iotmaker
ok - then this must be something in pymakr
but did you tried wifi AP+STA?
you then can connect to router and in the same time connect to Wipy/LoPy

thanks livius... yes thats the weird thing. it works with wifi, i can connect my laptop to the sipy wify and connect the pymakr without problem..

i will see what else i can do..

[livius]

@iotmaker
just curious
what you have connected on uart1? GPS, phone...?

[iotmaker]

gps...

i kind of found part of the problem...

the on the boot.py i had

from machine import UART
import os
uart = UART(0, 115200)
os.dupterm(uart)

and on my main.py

from machine import UART
import time
import pycom

uart=UART(1, pins=("G2", "G1") )
pycom.rgbled(0x000000)
uart.init(9600, bits=8, parity=None, stop=1)
while(1):
print(uart.readall())
time.sleep(1)

maybe having uart on the boot and main.py files is conflicting... gonna change them
