Set MAX_NUM_NODES super low in your variant.h, and see if it gives you enough headroom. I merged locally and attempted this. Getting errors ``` /home/jbennett/.platformio/packages/framework-arduinoststm32/system/Drivers/CMSIS/Device/ST/STM32WLxx/Include/stm32wle5xx.h:993:47: error: expected ')' before '*'...

Another flash saving potential is the unishox library. It's only actually used for ATAK packets. #ifdef it out of existence, to save a few more bytes.

I think the game plan is to modularize the S&F backend to support more devices and storage types.

Somewhat related is the desire to set precision levels for different channels. Possibly through a bitmask that gets AND'd with the location at https://github.com/meshtastic/firmware/blob/master/src/modules/PositionModule.cpp#L110 before sending the packet.

> I had originally envisioned that being an enum w/ flags We could do that with the GPS stuff, too. Maybe define high, mid, and low accuracy GPS flags.

I bet the GPS chip is actually sending an *empty* altitude value. TinyGPS doesn't have a code path for this, and ends up dereferencing an unset pointer. Working on a...

Given those values, @caveman99 is probably right. And the raw value is in 1/100 of a meter, so that checks out. Any chance you're 14 meters below sea level? Either...
