Re: Random ESP_ERR_NVS_NOT_FOUND from nvs_get_blob() sometimes?

Hi Charger, this looks a bit more like an issue in nvs. used_entries shouldn't be 0 if you set values already.

Re: Pass array in FreeRTOS Queue

Hi, I haven't tested it (yet, will do that tomorrow). But regarding the documentation, it's possible. Upon queue creation, you specify the size of each item in bytes. The queue will allocate the maximum amount of storage right from the beginning, no matter how many items are actually stored. Items p...
