lntrigger's Issues

M5Stack Core 2 Compatibility?

Love the project, been waiting weeks for everything to arrive, finally able to get things rolling.

Arrived at the part where the M5 displays a QR code. I scan, pay, see result in legend.lnbits.com, though, M5 stays on QR code screen and nothing happens. No LED. No refresh.

Is it possible because I ordered the Core 2, and not the Core 1 (as shown in your examples), that I am experiencing that freeze?

Thank you for everything!!!

M5stack fire

I have the M5stack fire. The portal launches and can I connect to the AP and configure wifi etc. But after processing I'm just seeing "ERROR" on screen. Don't really know where to go from here.

I am a beginner. i do not know what I made wrong.
is it a network pb or an invoice read key config ?
is the lntrigger.ino still compatible the lnbits.com ?
my feeling is that the ino does not access the server

any suggestion ?
