This repository contains the micropython WalterModem library.
This library is designed to consume as little energy as possible by making use of the FreeRTOS locking mechanisms and the hardware UART. There are not active wait situations which consume useless CPU cycles. Besides that the library does not allocate dynamic heap memory. All RAM is determined at compiled time. This makes debugging easier and mitigates unexpected out-of-memory situations.
You can find the setup guide here: Walter Modem; Micropython Setup
