Then transfer your modified library to flash. It would be good to change the name to another one, so that the import function does not load the built-in urequests library. Alternatively, you would have to look in what order and from which locations the libraries are imported.

The great thing about UIFlow/Micropython is that you can build most of the program in UIFlow and then switch to Micropython to make final adjustments.
The only issue is that you can't change back to UIFlow after adjusting because the code blocks won't exist for you added code.

@jesuslg123 If you use a programs like VStudio, Thonny and mu that you can add library directly to the M5Stack

Thanks, for the this project I was using the UIFlow editor with the UI programming language, do you think I can also replace the urequest version that is using this?
Also can you share with me how to upload with Visual Studio? Thanks

Hello, world101 I am very new here in the forum and want to control my M5STACK with "blynk" via UIflow symbols.
I use:
UiFlow V1.4.3
F5STACK fire, the red one.
blynk for Python v0.2.1 (esp32_LoBo)
MicroPython ESP32_LoBo_v3.2.24 - 2018-09-06 on M5Stack with ESP32

I have successfully worked through all the above points.
However, the dispaly from my M5STACK shows the following error message:

error
ImportError("no module named 'uiflow'",)

I think that I have not installed the above mentioned elements:
"machine, time, m5base, uiflow"

In the boot.py I have edited the following, as you have described above:
import sys
sys.path.append('flowlib/lib')
sys.path.append('/flash/blynk')
import machine, time, m5base, uiflow, BlynkLib

I would like to implement remote monitoring via iphon of my groundwater pump.
It would be nice if you could help me, please.

You’re not going to (easily) be able to use LoBo Micropython and the later versions of UIFlow. I think uiFlow v1.2.3 was the latest that LoBo was supported. Best thing would be to flash the official v1.4.4 firmware from M5Stack and use uiFlow v1.4.4.

Try that first, then try to import the Blynk libs and see if it works.

ampy -p /dev/tty.SLAB_USBtoUART -b 115200 mkdir /flash/custom
ampy -p /dev/tty.SLAB_USBtoUART -b 115200 put customLib.py /flash/custom/customLib.py

in boot.py:

import sys
sys.path.append('flowlib/lib')
sys.path.append('/flash/custom')

Then with uiFlow, you can use the execute block to have the choice when it gets imported (so you don't import it automatically when your program doesn't need it).

git clone https://github.com/vshymanskyy/blynk-library-python.git
cd blynk-library-python
ampy -p /dev/tty.SLAB_USBtoUART -b 115200 mkdir /flash/blynk
ampy -p /dev/tty.SLAB_USBtoUART -b 115200 put BlynkLib.py /flash/blynk/BlynkLib.py
ampy -p /dev/tty.SLAB_USBtoUART -b 115200 get /flash/boot.py > boot.py

Use vi to edit the first few lines of boot.py to look like this:

import sys
sys.path.append('flowlib/lib')
sys.path.append('/flash/blynk')

import machine, time, m5base, uiflow, BlynkLib

Copy the modified boot.py back to the m5stack:

ampy -p /dev/tty.SLAB_USBtoUART -b 115200 put boot.py /flash/boot.py

Connect to the serial interface via screen and reboot the m5stack. You should see the Blynk lib load at bootup.

Since m5stack moved from the Loboris fork of Micropython to the official Micropython v1.11 release, it seems the libs were also moved somewhere. With m5stack firmware v1.2.x, they used to be in /flash/lib, however now with firmware 1.3.x, that directory does not exist. If I try to create /flash/lib with ampy, the m5stack won't boot properly.

The above serial output during bootup shows something in flowlib, but I can't seem to access it. If someone could assist with where to put the custom libs, I could probably get Blynk working again.

I thought that was just me. I too tried to copy over blynk this weekend using vstudio but again had the same boot issue.

Not sure whether https://github.com/m5stack/M5Stack_MicroPython includes UI-Flow.

Any pointers?

th blynk. Have you tried putting the module on to the flash more than once? I've found ampy to be a little buggy at times, sometimes the copy wasn't successful sometimes it was.

Yes, flashed it couple of times and also tried by transferring the file via upyLoader. Same result. Blynk is very easy to use and it would be great with the convenience of uiflow and M5stack.
