Hi all, should the Reset pin on the RFM69 ever be populated to an IO pin on the ATMEGA328P ? Has anyone ever found a situation where the module locks up that a hard reset is needed? If I do populate the RESET pin, would that effect OTA or any other process in Felix's libraries?
Thanks all
IMO, if you plan to experiment with the RFM69 library and try different things, then having the ability to reset the radio is useful (note that it's not trivial to reset the radio). However, if you're using the standard library, you probably won't have a need to reset the radio.
I've wired the reset line on most of my custom motes, but haven't used them other than a few very obscure cases where I probably shouldn't have been doing the mean things I was doing to the radio...

I reinitialized the radio if its ever failed and that seemed to do the trick, just wasn't sure of the unknown.
Okay, better for me to keep a GPIO free! :)
Thanks
The RST pin is actually active high, driven as open source, and with an internal pull-down. If you drive it from a processor you should drive high for the minimum reset time, then tri-state and wait for it to go back low. The radio itself drives this signal high during its reset operation and will release it when it's completed.
