WiFi:bit firmware upgrade for ESP8266 AT version

TECHNICAL SUPPORT Communication Modules

Customer:

We have several WiFi:bit modules from a previous generation and need to upgrade the firmware to use new services and protocols that newer versions support, such as NTP. The existing modules have these versions:

AT version 1.3.0.0 (14.07.2016)
SDK version 2.0.0 (5a875ba)
v1.0.0.3 (13.03.2018)

What would be the recommended and least invasive method for upgrading the firmware, and which AT BIN firmware version is recommended for this module?

Dobar dan!

Imamo nekoliko, vrlo korisnih, WiFi:bit modula prethodne generacije (od prije nekoliko godina) i javlja nam se potreba ažuriranja firmvera zbog korištenja novih servisa i protokola koje nove verzije sadrže (NTP npr.). Na postojećim modulima je slijedeća verzija:

AT version 1.3.0.0 (14.07.2016)

SDK version 2.0.0 (5a875ba)

v1.0.0.3 (13.03.2018)

Koja bi bila preporučena i najmanje invazivna metoda upgradea FW-a, te koja je preporučena AT BIN verzija FW-a za ovaj modul?

As mentioned in the previous message, this is about the firmware specifically—AT BIN support for the ESP8266 SoC on the WiFi:bit module. The existing firmware is from 2016. That version does not have many advanced options implemented, nor does it include many fixes that were identified later.

Dobar dan!

Kao što i piše u mailu - riječ je o firmveru, konkretno AT BIN podršci za ESP8266 SoC na WiFi:bit modulu. Postojeći firmver je iz 2016. U toj verziji nisu implementirane mnoge napredne opcije, kao niti dobar dio ispravaka koji su naknadno uočeni.

Soldered Support:

To upload new firmware, connect a USB-UART converter to the programming pins on the board and use the ESP tool to program the new firmware onto the ESP8266.

You can use the latest stable version that suits your needs and includes the features you require. As you noted, newer versions have many things that were not previously supported.

Original message (Croatian)

Za uploadanje novoga firmwarea potrebno je spojiti USB-UART konverter na pločicu na pinove za programiranje te pomoću ESPtoola za programiranje staviti novi firmware na ESP8266.

Verziju možete staviti zadnju stabilnu koja vam odgovara sa svime što se u njoj nudi (napisali ste da nove verzije imaju dosta stvari koje nisu prethodno podržane).
