Not receive messages in gateway mode

[zetapersei]

Hi,
I tried the gateway example together with the node example with two esp32 + RFM95 at 868 Mhz. The node is working fine, but the esp gateway is not receiving any messages. All parameters are the same (SF, Freq, ...).
I changed the gateway source as follows:
`LoRaNow.send (); //added

LoRaNow.onMessage (onMessage);

LoRaNow.gateway (); `

and it works correctly. The gateway function appears to not initialize the hardware correctly.

Thanks.
