NVS Value Too Long

Postby lmagalhaes » Tue Apr 07, 2020 5:28 pm

Hi there,

I'm trying to store a byte array in non volatile memory, but I'm always getting the ESP_ERR_NVS_VALUE_TOO_LONG error... Here is the code:

Code: Select all

typedef struct {
	uint8_t month;
	uint8_t year;
} prodDate;

prodDate productionDate;

Code: Select all

productionDate.month = spp_data[5];
				productionDate.year = spp_data[6];
				
				
				err = nvs_open(STORAGE_NAMESPACE, NVS_READWRITE, &my_handle);
				
				if(err != ESP_OK){
					ESP_LOGI(SPP_TAG, "something went wrong 1");
				}
				
				nvsSize1 = sizeof(productionDate);
				ESP_LOGI(SPP_TAG, "nvssize = %d",nvsSize1);
	
				err = nvs_set_blob(my_handle, "prod_date", &productionDate, &nvsSize1);
				
				if(err != ESP_OK){
					ESP_LOGI(SPP_TAG, "something went wrong 2");
					ESP_LOGI(SPP_TAG, "%s",esp_err_to_name(err));
					if(err == ESP_ERR_NVS_INVALID_HANDLE)
						ESP_LOGI(SPP_TAG, "invalid handle");
					if(err == ESP_ERR_NVS_READ_ONLY)
						ESP_LOGI(SPP_TAG, "read only");
					if(err == ESP_ERR_NVS_INVALID_NAME)
						ESP_LOGI(SPP_TAG, "invalid name");
					if(err == ESP_ERR_NVS_NOT_ENOUGH_SPACE)
						ESP_LOGI(SPP_TAG, "not enough space");
					if(err == ESP_ERR_NVS_REMOVE_FAILED)
						ESP_LOGI(SPP_TAG, "remove failed");
					if(err == ESP_ERR_NVS_VALUE_TOO_LONG)
						ESP_LOGI(SPP_TAG, "value too long");
				}
				
				err = nvs_commit(my_handle);
				
				if(err != ESP_OK){
					ESP_LOGI(SPP_TAG, "something went wrong 3");
				}
				
			nvs_close(my_handle);
Can anyone help me figure this one out ? It's the same with a struct and when I use a uint8_t productionDate[4] array...
