AT Binary Lists¶
Each of the linked above ESP-AT-Bin files contains several binaries for some specific functions, and the factory/factory/xxx.bin is the combination of all binaries. So user can only download the factory/factory_xxx.bin
to address 0, or several binaries to different addresses according to ESP-AT-Bin/download.config
.
at_customize.bin
is to provide a user partition table, which lists different partitions for theble_data.bin
, SSL certificates, andfactory_param_XXX.bin
. Furthermore, users can add their own users partitions, and read/write the user partitions with the commandAT+FS
andAT+SYSFLASH
.factory_param_XXX.bin
indicates the hardware configurations for different ESP modules (see the table below). Please make sure the correct bin is used for your specific module. If users design their own module, they can configure it with reference to theesp-at/docs/en/Compile_and_Develop/How_to_create_factory_parameter_bin.md
, and the binaries will be automatically generated after compilation. When users flash the firmware into module according to thedownload.config
, thecustomized_partitions/factory_param.bin
should be replaced with the actual module-specificcustomized_partitions/factory_param_XXX.bin
. UART CTS and RTS pins are optional.- ESP32 Series

ESP32S2-MINI Series GPIO17, GPIO21, GPIO20, GPIO19 factory_param_MINI.bin
- ESP32-C3 Series
Modules UART Pins (TX, RX, CTS, RTS) Factory Parameter Bin ESP32-C3-MINI Series GPIO7, GPIO6, GPIO5, GPIO4 factory_param_MINI-1.bin
- ESP8266 Series
Modules UART Pins (TX, RX, CTS, RTS) Factory Parameter Bin ESP-WROOM-02 Series (ESP8266 Default Value) GPIO15, GPIO13, GPIO3, GPIO1 factory_param_WROOM-02.bin
ble_data.bin
is to provide BLE services when the ESP32 works as a BLE server;server_cert.bin
,server_key.bin
andserver_ca.bin
are examples of SSL server‘s certificate;client_cert.bin
,client_key.bin
andclient_ca.bin
are examples of SSL client‘s certificate.
If some of the functions are not used, then the corresponding binaries need not to be downloaded into flash.
