@Anticimex I had to turn off MY_DEBUG to add the encryption directives. I also moved everything back to version 2.3.1 as I was still seeing some weird stuff going on like msg-type 169 (unknown) and attempts to route through nodes that don't exist. These things I guess may have been due to high ram usage. I think I was at about 78% w version 2.3.2 and basic encryption enabled but now... Sketch uses 21542 bytes (70%) of program storage space. Maximum is 30720 bytes. Global variables use 1108 bytes (54%) of dynamic memory, leaving 940 bytes for local variables. Maximum is 2048 bytes. @Yveaux - I don't expect that it would have been high ram usage causing my initial issues as I wasn't using any encryption or signing before. I started seeing these problems when I moved to 2.3.2 but as I had also been dealing with a new sensor on my first Sensebender Micro, I wasn't sure what might be causing the problems. What do you think might have caused the received data type to flip from a float to an unsigned integer?

@mfalkvidd Thank you - MY_DEBUG_VERBOSE_OTA_UPDATE does look like it's exactly what I was looking for. Further looking into the code here though, it would seem that it gets defined automatically if we define MY_DEBUG. Turn it around, when we define MY_DEBUG, we should see verbose FOTA (+ Core, Transport and Gateway) information in the serial log output. I'll attempt some more testing tonight to see what I can see.
