arduino-esp32/esp-idf and v1.0/v2.0 version retrieval differences

[drws]

This is probably more of a feature request than a bug report, concerning both v1.0 and v2.0 branches.

Esp.h provides a runtime function getSdkVersion(), a wrapper for esp-idf's esp_get_idf_version(), which reads version data from esp_idf_version.h containing ESP_IDF_VERSION_* macros.

A similar story is arduino-esp32 version, the esp_arduino_version.h providing ESP_ARDUINO_VERSION_* macros. It has been added only recently to v2.0 branch only. Firstly, I propose esp_arduino_version.h is also ported to v1.0 codebase so the two major Arduino SDK versions are compatible in such basic regard.

However, the arduino-esp32 does not contain getSdkVersion()-analogue function containing its version string, available at runtime. A getSdk2Version() if you will. Second proposal of this issue is that such function is added to v2.0 and v1.0 branches.

This would also make arduino-esp32 version as accessible as esp-idf one is, without needing to include esp_arduino_version.h. Such basic debugging information should probably be most easily accessible.

Status update of this issue:

• we have now version in corresponding headers
• we need to check matches and what we can do next (need review)

Status update:
We now have headers and files with all versions, but there is nothing we can do for older released versions.

I'm closing this issue.
