If esp_now_send fails, readyToSend never becomes true again #14

I believe the logic expects that esp_now_send will always call tx_cb, but I'm not sure that will happen in all error cases. That means readyToSend can stay false and block any more sends from happening.

I think I am having this issue right now actually.

I trying to use WiFi at the same time and that causes ESPNOW to give this error "E (12712) ESPNOW: Peer channel is not equal to the home channel, send fail!".

After this error I get 3 broadcasts out and then it seemingly does not get ready again.
