@dario said in UIFlow 1.6.6:

@jesuslg123 I'm using the version 1.6.6 with both StickC and SticC Plus without any issue

Are you using Bluetooth on StickC with 1.6.6? They mentioned Bluetooth is still not supported

@m5stack Thanks. Is there any plan for M5StickC?

Hellos,

That
* BLE bug fix.
mean bluetooth is now supported on UIFlow micropython firmware for M5StickC?

If yes, could you shared a simple sample please?

Thanks

Hello,

I frequently code in Mac OS and I have found that the copy paste feature does not works on the IDE Mac OS version.

• Copy text from any other app (browser, notes, ect)
• Open UIFlow IDE
• Set an string
• Paste the content you copied before (this fails)

It is a known behaviour, will be fixed?

Thank you.

I have created my own wifi GoPro remote controller, that it should work with all the model starting from the GoPro Hero 3+ (some changes may be required). I have tested it with the GoPro Hero 7 Silver but it should also work without any change with the white and black version.

GoPro in the latests version only enable GoPro remote support for the black models, even all of them are capable. As I don't have a black version of the GoPro I created my own controller.

I have used an StickC with the strap and Blockly, but it becoming a mess because of the size of the idea, I would like, some day, port it to Arduino or Python.

Here is the source code and instructions, I really hope you like and contribute!

Is there any official update on this topic? Is bluetooth gonna be supported? Thanks

Hi, thanks for the answer, but this is not actually helping in the issue. I may have explained wrong.

• I'm using blockly and the screen get mess with so many blocks around used by the app.
• Use custom blocks would not help too much as I would need to write my own python code plus also I would drag the block inside the screen also.

So lets say my idea is having blockly have various screen for the same app to organize the blocks in sections/pages.

Thanks

Hello,

I would like to know if there is plan to allow have programs splited in multiple files on UIFlow Editor, like a real app with clases etc. I have the feeling that the content on the editor grows to quickly and search for things can be difficult. Having multiple files with in the same app could be very helpful.

Thanks,
Jesús.

So, I could workaround this issue after some work and before close and forget this thread here forever, let me share it:

The problem:

• GoPro wifi API is not fully following the HTTP protocol specifications.
  • Headers and body content is separated by \n instead of \r\n
• uRequests library is very strict on response parsing, while mostly any other libraries/browser/etc handle requests with some "malformed" bodies, uRequests does not.

UIFlow IDE solution:

• Upload to the Stick5C the modified version of uRequests
  
• Override the uRequests library usage with a new import using execute code block.
  
• From that moment on (only on this app) it will use the modified library.

No UIFlow IDE solution:

• Stop using UIFlow IDE 😢
• Upload to the Stick5C the modified version of uRequests
• Use Visual Studio code or any other IDE to continue the development.
• Override the uRequests library usage with a new import on the code.

I hope this is useful to someone else, any suggestion is also more than welcome.

Thanks 😄

Just finished to write it down all this and I think I the failed attempt it could work using the execute code block to make the import override and keep using the UIFlow IDE 😱 That this makes sense?

New attempt

• Upload to the Stick5C the modified version of uRequests
• Keep using UIFlow IDE 🎉
• Override the uRequests library usage with a new import on the code using execute code block.

I will try it and update you.

@ajb2k3 said in Adding external libraries via uiflow:

@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

Is this method valid to replace libraries like urequests? I found a "bug" on the current implementation and I would like to replace the one that comes with the UIFlow firmware to workaround the issue. Is that possible or in any other way?
Thanks!

@robalstona said in HTTP Get - Empty response body:

I use urequests in raw python and i use something like this code below to parse response (i delete some unwanted characters by replacing it with empty string)

response = urequests.get('http://...')

if response is a json

data = json.loads(response.text.replace('STRING_TO_REPLACE', 'NEW_STRING')

other text

data = response.text.replace('STRING_TO_REPLACE', 'NEW_STRING')

The problem is that the library is breaking the response before return it to me. When doing
esponse = urequests.get('http://...')
at that point the response body is already broken, that why I need to customize the library. It in deeper level the issue.

I can not edit the post, sorry.

Sample of the response bodies:

Most common and working

See its use all the time \r\n

GoPro sample, and not working

See it ends with \n\n b'HTTP/1.0 200 OK\r\n

Thank you for your answer, after all day testing I found the issue:

The urequest library, which is used for the firmware, has an implementation that fails with the GoPro requests due to how it cleans the request body.

During the clean up process of the body its split content by if not l or l == b"\r\n":,
which probably is ok for most of the requests, but not too flexible or safe, but the GoPro use \n\n to split the Content-Type line from the actual body response.

So in order to fix the issue, I need to modify the urequests implementation, from:
if not l or l == b"\r\n":
to
if not l or l == b"\n" or l == b"\r\n":
with this change, everything works fine.

So my question is, it is possible to replace the urequests library included in the firmware with my fork/custom changes? I have seen how to load external libs, but I don't know the path for the urequest lib.

Thank you!

Hello,

I'm having a really weird issue where the response body of a GET http request is empty but it should have a JSON object.

The request is done to a GoPro camera, using the Wifi API, and it's actually works, I can see my GoPro changing the state and the request response is 200, but the body is empty.

I have been doing some testing and I found a pretty weird behaviour:

• Any request to the GoPro API is getting empty body response using UIFlow/Microphyton (while body has content doing the request from my computer).
• Serving a GoPro JSON object from my computer it works fine on UIFlow/Microphyton, response has content.
• Any requests to my GoPro using Arduino IDE with WifiClient lib is getting the valid json response.

I'm totally stuck here, not sure if M5Stack firmware or urequest lib has some kind of bug or whats it is happening. Any help is more than welcome :)

Thanks!
