gpio23 & lora receive

[kjm1102]

I'm running lora on a TTGO board. lora uses lots of gpio ('miso':19, 'mosi':27, 'ss':18, 'sck':5, 'dio_0':26, 'reset':14) but as far as I know 23 is not one of them. But when I try to use it as a relay drive, rly=Pin(23, Pin.OUT), the board refuses to receive lora packets (still sends OK). Easy fix, move the relay to gpio 15 instead.

Still I'm left scratching my head as to why? Anybody know why gpio 23 is off limits?

My bad, got my wires crossed (literally), 23 is lora reset on the TTGO.
