OTA a microcontroller using EC200 module

Hello,

We are looking to perform OTA of our microcontroller using EC200 over UART. The bin file is fairly large (~2M) and space is limited on the EC200 module (~700kb) . What is the recommended approach ? Right now we are using HTTP, but plan to use MQTT in the future.

Thanks.

Depending on the information you provide, you can use HTTP methods, but your mcu still needs to cache the upgrade package, and the module’s FILE system cannot fully store the complete upgrade package
