Hi there, We recently purchased the RTK Surveyor for testing reasons. We were trying to compile the Arduino firmware but it returns some errors. Please could you give us some suggestions in order to finally compile the Arduino firmware? It seems like some macros are not defined, they are not found in the whole project, is it something we need to add? Error Message: * * * WARNING: library JC\_Button claims to run on avr architecture(s) and may be incompatible with your current board which runs on esp32 architecture(s).

> was not declared in this scope That generally means you haven't installed one or more libraries required by the code you're trying to compile.
