I am trying SPIFFS example with “partition label” instead of using NULL for .partition_table in esp_vfs_spiffs_conf_t My spiffs partion is as below in my partition table: storage, data, spiffs, , 0x6000, This is my code: const char *part_label="storage"; void files(void) { ESP_LOGI(TAG, "Initializin...

For two way communication in IoT world, the preferred and most used protocol is MQTT (instead of http). A few desirable features of MQTT are: Small code footprint (to make it easy to implement in small devices) Low power consumption Low bandwidth consumption Low latency Use of a publish/subscribe (“...

Thanks WiFive for response. Good clue, “erase only when run out of space” to reduce at least erase cycle. Just wondering, do people often use this approach in production (save data on flash for a while for later uploading on server) :? :shock: ? Just gathering courage to use this approach. :D :D

I want to take reading of a sensor every 5 minutes and save it on flash. Then every 24 hours I will send it to server via WiFi. I read somewhere in this forum that there is a limit of about 10000 write/erase cycles on flash of ESP32 WROOM. (ESP32 WROOM probably uses GD25Q32C and according to its dat...

Currently I am using ESP-IDF command prompt to build, configure, flash etc. How can I use windows Powershell to run commands like idf.py menuconfig etc.?

I am using idf version 4.0 with CMake.

Type casting sta_config.sta.ssid and sta_config.sta.password to (char* ) solved the problem: wifi_config_t sta_config = {}; strcpy((char *)sta_config.sta.ssid, vSSID); strcpy((char *)sta_config.sta.password, vPW); instead of wifi_config_t wifi_config = { .sta = { .ssid = aa, .password = bb }, };

I am building wifi example esp-idf/examples/wifi/getting_started/station/. I only changed these lines: char aa[]="myssid"; char bb[]="mypassword"; wifi_config_t wifi_config = { .sta = { .ssid = aa, .password = bb }, }; Now I am getting this error: ../main/station_example_main.c: In function 'wifi_in...

I used ESP-IDF Tools Installer version 2.3 to successfully install required tools and esp-idf 4.0. I can configure, build, flash projects if they are in some sub folder of esp-idf folder. But I work on projects which are in some folder other than esp-idf folder. How can I use esp-idf command prompt ...
