@crami25 My sensor locations are out in the bush, where no cell signal, nor LoraWan gateway is available. LORA 9xx might be able to connect
env. data aquisition, or do emergency signal calls.

RFID2 tag writer using UIflow2, or mpy
My hardware platform is a Cardputer. I would appreciate to get a working mpy code example, or UIflow2, that shows how to format the data and write it onto an RFID tag with RFID2 unit. Getting an error when using the bytearray data format during a write operation. Please also clarify the addressing scheme and length of the data chunks for write operations.

Battery Monitor at Cardputer UIFlow2 Hardware Functions?
At Cardputer and UIFlow2 firmware, does it deliver a "Power" function for battery monitoring? Not able to find the power function under 2.0.1 firmware. It is also not part of the optional hardware modules. Thanks for support.

RE: MQTT and AWS IoT Support in UiFlow 2.0
@falbriard Sorry, I found MQTT services as an optional software choice available under UIFlow2 and among other useful network services. Thanks.

RE: MQTT and AWS IoT Support in UiFlow 2.0
MQTT protocol support is essencial for IOT and should be part of the UIFlow2 blockly code. In the M5 core2 and UIFlow version 1, I've used it extensively for collecting sensor data together with the MQTT Adafruit server and Python API data functions (select criteria, delete).

RE: Error at NTP module on UIFlow2 and Cardputer: Missing timezone
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?

RE: UIflow 2.0.1 on Cardputer not booting
@ajb2k3 Thanks, got it working with the black USB cable of the Core2 device. The sequence used was: reset on the Cardputer, connect USB cable, burn, erase, configure, back to burn, take note of MAC address and login pairing, again burn until completion. The device will boot at completion message. Next steps are: to make it talk to UIflow2 programs via serial, or Wi-fi link run function.

RE: UIflow 2.0.1 on Cardputer not booting
Still getting a black screen after the burn. I've resett
ed the Cardputer, then called burn, erase (ok), configure with the final firmware transfer (ok, green confirmation message), disconnected the USB C cable, power-on which shows no display message, just a black screen. The same with the reset button, short or long press. UIflow2 version is 2.0.1 and ESP32 FN8. Any idea is welcome. -
UIflow 2.0.1 on Cardputer not booting
Was able to install latest M5burner and download, configure, burn the image on the Cardputer device. After that the firmware does not activate. Other demo apps worked perfectly. Any hints How to fix It?
