Hi,
If you pull up Pin2 (GPIO2) with 10k to 3.3V, Wireless Stick Lite won’t connect to arduino:
Connecting……………_____…
If you leave Pin2 floating or pull it down to GND, arduino will connect immediately.
Interestingly, schematic doesn’t show any internal connections with Pin2.
I need this, because I must connect i2c to these pins, and i2c need a pull-up.
After programming, I can use Pin2 for i2c.
Tested with 433 and 868MHz Version, also the newest.
