@_andreas_ said in CoreS3 & HTTP Request block: urequests import error:

Hi,

FYI: I've got a response from m5stack support regarding this issue:

Below issue is caused by the mpy version changing. We may fix it by next version, which should be next Friday. Thx!

Can confirm, this is now fixed!

@mchott the line error doesn’t always report the correct line unless you know how to read it. I recently found a syntax error due to quote mark formatting

@felmue That seems to have fixed the issue. Thanks for your help.

@teastain Ah Ok thanks, I avoid arduino like the plague so didn't notice.

Hopefully that means that people can read the example and simply port to arduino.

Hello @falbriard

all you can do is reading GPIO10 to get battery voltage. See documentation here - section PinMap - Keyboard&Battery Detect.

The charger IC cannot be queried as the two outputs CHRG and STDBY are not connected as you can see in the schematic.

Thanks
Felix

Yes, the endpoint responds almost instantly. Also the status code immediately comes back as as '200'.

@falbriard Sorry, I found MQTT services as an optional software choice available under UIFlow2 and among other useful network services. Thanks.

I observe that there seems to be an NTP init step at the begin of the default UIFlow2 firmware startup, as the required arguments are part of the burn and configuration options. There is no more NTP section in the UIFLow2 blocks but a so called “Time” section thats delivers the “set timezone” command, which is in error. Please confirm the NTP was moved into the firmware and "Time" and also check why the “timezone” module was not loaded by the firmware. Thanks for support. Shouldn't there be a mandatory Wifi connection setup before issuing an NTP request? Further, I got NTP data but with strange return values like: 2054,2,20,12,11.. . Why?

@wsanders if you are programming in Micropython (the language behind UIFlow) use thonny, otherwise forget Arduino and use visual studio

UIFlow2 for Core/Go/Fire

@falbriard glad you have it working.
In UIFlow2 there is now the Project zone. I'm writing a book on UIFlow2 for the CoreS3 (but the instructions works on any S3 series device) you can find a work in progress copy on face book but I'm slowly porting the books examples to Project Zone.

Hello @txinto

you can wrap the get key block in a try / except block. See example M5Dial_NVS_UIFlow2.0.1 in the UIFlow2 Project Zone.

Thanks
Felix

Hello @ajb2k3

nice! And thanks for the tip with the # before the note.

Thanks
Felix

Hello @PPKOVY

I put some I2C blocks together to control the 4 relays unit from M5Dial.

You can find the example in the UIFlow2 cloud - Project Zone. It is called: M5Dial_4RelayUnit_UIFlow2.0.1

Thanks
Felix

I don’t know of any drag and drop Micropython libs as they were written in c for direct compilation into firmware

You will need to have the stock latest version of UIFlow/Micropython and work from that version in thonny

Hi,

I am new, but I have been poking around since I experienced the urequests library not found error.

I REPL'd into my Core3,, and sure enough, it wasn't there, but there was one called requests.

I did some poker with the code in UiFlow and read many Google answers, but I managed to get it to work. I ended up with the HTTP request in a code block.

http_req = requests.request(
method='POST',
url='http://192.168.1.51/json/state',
headers={'Content-Type':'application/json'},
data='{"on":true,"bri":255, "v":true, "seg":{"fx":"r", "pal":"r"}}'
)
http_req.close()

It seemed to work for me, but I would prefer to get it working correctly.

Hi ajb2k3,

Thank you for your kind reply.
I can do it with following process as you said.

Plug in USB cable Hold Boot button (RST button) on coreS3 for over 5seconds LED turned to be green Enable to burn coreS3 UserDemo with M5Burner !!!

Thank you again.

@robski please reread the post as I have actually mentioned those details.

@ajb2k3 thanks for answering.
Do you know what the final http function is that you tell me?
