Upgrading Grove-UART WiFi V2 to latest ESP-AT firmware

Sat, 17 Dec 2022 00:00:00 +0100

The Grove - UART WiFi is a UART transceiver module from Seeed Studio featuring the ubiquitous ESP8266 IoT SoC. With integrated TCP/IP protocol stack, this module lets your micro-controller interact with WiFi networks with a dedicated set of AT commands.

Unfortunately, these modules come from Seeed Studio with a quite outdated version of the ESP-AT command set. The module I bought through DigiKey was delivered with the ESP-AT 1.6 release, that lacks several interesting features available in the more recent versions.
