flashing ESP-WROOM-02D-N4

[ARG2004]

Hi, tried to use HTTP specific command in ESP-WROOM-02D-N4

getting below responses


AT+GMR

AT version:1.7.3.0(Mar 19 2020 18:15:04)

SDK version:3.0.3(8427744)

compile time:Mar 24 2020 16:16:12

Bin version(Wroom 02):3.0.3

OK



CMD:

AT+HTTPCLIENT=3,0,”http://httpbin.org/post”,"httpbin.org", ... ld2=value2"

Response:

AT+HTTPCLIENT=3,0,”http://httpbin.org/post”,"httpbin.org", ... ld2=value2"

ERROR

Do we have support for httpclient command with ESP8266?

tried to upgrade the AT instruction set by flashing the module using After flashing ver ESP-WROOM-02-AT-V2.2.1.0 and ESP-WROOM-02-AT-V2.2.2.0
with following settings
--flash_mode dio --flash_freq 80m --flash_size 2MB 0x8000 partition_table/partition-table.bin 0x9000 ota_data_initial.bin 0x0 bootloader/bootloader.bin 0x10000 esp-at.bin 0xF0000 at_customize.bin 0xFC000 customized_partitions/client_ca.bin 0x106000 customized_partitions/mqtt_key.bin 0x104000 customized_partitions/mqtt_cert.bin 0x108000 customized_partitions/mqtt_ca.bin 0xF1000 customized_partitions/factory_param.bin 0xF8000 customized_partitions/client_cert.bin 0xFA000 customized_partitions/client_key.bin

sometimes it gives boot mode:(3,4) or boot mode:(3,7)

Let me know,
1. Do we have seperate bin files for ESP-WROOM-02D-N4, as download available is for only 2MB flash version
2. Does these bin files work with 4MB flash, is their any changes required in address?

Hello @ARG2004 ,
1. The firmware in the v1.7.x series, along with the corresponding SDK, does not support HTTP functionality.
2. For firmware versions v2.2.1.0 and v2.3.0.0, HTTP commands are not supported by default due to memory constraints, but you can enable HTTP support by building esp-at project: python build.py menuconfig > Component config > AT > AT http command support
3. I am providing an AT firmware that includes HTTP functionality in the attachment, please check it.
4. Alternatively, you can compile the project based on the release/v2.3.0.0_esp8266 branch to enable HTTP commands. Compilation instructions can be found here: https://docs.espressif.com/projects/esp ... le_it.html
