<![CDATA[Frequent use of pycom.nvs_set.]]>Hi,

Does anyone know what the flash write durability is like when using pycom.nvs_set ? I think there is some wear levelling in force, but does that only apply at the filesystem level when writing to internal flash ? Or is it safe to write a counter value for example so it is preserved ?

There is wear levelling mechanism on nvs_set, it uses the Non-volatile library from ESP-IDF: http://esp-idf.readthedocs.io/en/latest/api-reference/storage/nvs_flash.html
