Send data to server

Question

I'm using the Nordic Thingy:91 and my goal is to send AT commands via UART from an ESP32 to the Thingy:91, in order to send data to a PHP file located on a server. 
 
 I follow the getting started ( https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/working_with_nrf/nrf91/thingy91_gsg.html ) and using the Programer i upload the img_fota_dfu_hex/thingy91_serial_lte_modem_2023-03-02_8f26142b.hex. 
 I have tried to send data to a php file located on a server through the "LTE Link Monitor" of "nRF Connect for Desktop" but all time it fails. 
 I have doubts if I'm using the correct configuration for the Thingy:91. Which .hex file should I use to achieve it? Should I use the thingy91_at_client_2023-03-02_8f26142b.hex or the thingy91_serial_lte_modem_2023-03-02_8f26142b.hex? 
 Which AT commands should I use to send data to PHP? I have used the command 'at+cipstart' with 'at+cipsend', but it fails. 
 
 Thanks for all

Hi Roger, 
 I suggest you use thingy91_fw_2023-03-02_8f26142b\img_fota_dfu_hex	hingy91_serial_lte_modem_2023-03-02_8f26142b.hex since it has more AT commands supported. AT Client only have AT commands originally supported by modem firmware. nRF9160: Serial LTE modem — nRF Connect SDK 2.3.0 documentation (nordicsemi.com) has more AT commands supported on application levels in addition to basic AT commands supported by the modem, you can find the usage of AT commands from its page, but at+cipstart' and 'at+cipsend' are not supported. You could use TCP/UDP/FTP/MQTT/HTTP and so on to transfer a file to your server, depending on which protocols your server supports. SLM has support for the most commonly used protocols. 
 Best regards,
