Hi @riztronic
We have fully tested the Arduino code running normally and without a problem!
You can get the newest code here:
https://github.com/m5stack/M5-LoRa-E220/blob/main/examples/P2P_TX_RX/P2P_TX_RX.ino
The test video is here:

The problem may be that your TX/RX pins are reversed

import os, sys, io import M5 from M5 import * from hardware import sdcard label0 = None def setup(): global label0 M5.begin() Widgets.fillScreen(0x222222) label0 = Widgets.Label("label0", 21, 46, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu18) sdcard.SDCard(slot=2, width=1, sck=18, miso=19, mosi=23, cs=4, freq=1000000) label0.setText(str(os.listdir('/sd/'))) def loop(): global label0 M5.update() if __name__ == '__main__': try: setup() while True: loop() except (Exception, KeyboardInterrupt) as e: try: from utility import print_error_msg print_error_msg(e) except ImportError: print("please update to latest firmware")

Thanks

@zoner I see... One year passed and still no label rotation. I just installed UiFlow2 firmware but I think I'll back to first edition.

@mb How do you get NTP time in UiFlow2? O cannot see NTP module. It was in previous UiFlow, but now I can't find it.

Ensure you're using the correct credentials and that your access permissions are set correctly. Try resetting your password, check if the repository is private, or contact your project administrator for assistance with authentication issues.

@cloudmonkey it’s on my work list for the documents

@jondaaa
refer to examples in Project Zone

Hello @nmstack

please have a look at this thread.

Thanks
Felix

@aivarannamaa I just ran into this issue, and your advice helped (MBA M2 Sequoia 15.2) – thank you!

Well, I think I've made a beginner's mistake. I didn't restart PaperS3.
After flashing it, I pressed the reset/boot/... button and it displayed the UiFlow page on PaperS3.

Thanks for your help Felix

To use HTTP GET in uiflow2 for fetching JSON, use the "HTTP Request" block. Set the method to "GET" and provide the URL of the API. Then, process the response with a JSON block to parse the data.

The only way I found was to copy the Python code from UIFLOW2, paste it in Thonny and save it as a .py file. Then upload it using the WebTerminal in UI FLoW 2 interface

Hello @digiajay

ok, understood.

Well, you cannot set a different EOL character and therefore you cannot use UART block read line.

However you can use block count of available and read 1 bytes etc. to read chars sent from your device. As long as the char received is not your EOL char, append them into a buffer. And when you receive your EOL char do something with the chars accumulated in the buffer, then clear the buffer and start over.

Thanks
Felix

I just tested it again but with the firmware 2.1.0. It works on pin 1, 2 and 10. I think there is a bug in the firmware 2.1.9....

@kuriko
The error occurs in version V2.1.9 and V2.1.8. Version V2.1.7 works.
