The problem here is that none of the default fonts have the full font set, nor are Unicode compliant.
However, on UIFlow 1.13, and in my case the Fire board, I have a font "Unicode 24". This one actually supports the pound symbol just fine.

I suggest best if you are trying to make a UI to import a separate PNG for the GBP symbol and place it where needed.

Hello @felmue

Thanks for your note. You're completely correct.
I've set the DIP switch to 5V. When in that configuration
With the COM.LoRaWAN868 v2.0 connected to the Fire board and it's battery (in my case M5GO battery + a BATTERY 13.2 for long life), I get 5V going into the green board from the main PCB. See:

And as you say there is a regulator which drops the voltage to 3.3V (in my case ~4.9V in, then I see 3.28V and 3.3V at the test pads but that could be due to my cheap meter).

So then, I guess the COM.LoRaWAN868 v2.0 should actually work without any additional power source? I'm going to test that next. It should as I think, as aside from the voltage regulator, the green board doesn't seem to have anything active components on it.

The main board is a bit confusing as it also seems to have unused elements wherein one could also have a microphone MIC and a SPKR connected to it, but these elements remain unpopulated. I wonder what that was for.

Thanks!

From what I understand, the COM.LoRaWAN868 v2.0 module has 5V power requirements due to the LoRAWAN chip. To make this work, one thus has to power, via the provided 5.5mm barrel connector. This connector, depending on DIP switch settings can handle input of either 12VDC or 5VDC . In the case of 12VDC, the JW5033H voltage regulator IC steps down the voltage to the needed 5VDC.

Now I am wondering a couple of things:

• Is 5V power absolutely necessary to get this module working? Is this needed due to the requirements of the particular LORA chipset?

• If I power the module with the 5V, via the barrel connector, does this power the M5Stack device as well? (in my case I am using a Fire)

• If 5V is required, then could I not just get a 3v To 5v Boost Converter and wire it into the power provided by the battery in the Fire?

Thanks!

I have an M5 Fire. I am trying to get a Bluetooth BLE 2D/QR code scanner connected to the Fire using UIFlow (in HID mode). This has not gone well. I am wondering :

• If I am developing in UIFlow over WIFI, does this effectively stop BLE/Bluetooth from working because Bluetooth and WIFI can't work at the same time?

• Is it possible, within UIFlow to turn WIFI off completely so that BLE can own the antenna and work? (even with Execute code?)

• Has any one else managed to get something like this to work?

Thanks!!!

For anyone wondering, this thread is for the old Version 1.0 of the https://docs.m5stack.com/en/module/comx_lorawan, and NOT the Version 2.0 https://docs.m5stack.com/en/module/comx_lorawan868_2.0. In the 2.0 version there are DIP switches to direct the GPIO pins as required.
