# Walter Modem Driver for ESP-IDF ## Overview This component contains the WalterModem library which is used to use the Sequans GM02SP modem which is found on the Walter module. The Walter module is a fully certified modem module (CE, UKCA, FCC, IC, RCM) which is designed to be integrated in a cellular IoT product. Walter combines LTE-M, NB-IoT, WiFi, BLE and GNSS in a single module and runs on the ESP32-S3 MCU with 2MB of PSRAM and 16MB of flash memory. ## How to use This is the easiest way to use Walter Modem component. ```bash idf.py add-dependency "dptechnics/walter-modem^1.1.0" ``` To use this component inside your project, you must download the content of this repository to a convenient folder. Please ensure that the folder path is not excessively long (especially for Windows users). Create the `idf_component.yml` file inside the `main` folder of your project, or copy and modify `idf_component.yml` from one of the examples, and change the path to the Walter Modem component (`walter-modem`) folder. ```yml dependencies: walter-modem: path: <path_to_the_folder> ``` ## Contributing We welcome all contributions to the software via github pull requests on the [walter-esp-idf repository](https://github.com/QuickSpot/walter-esp-idf). Please take the design strategies in mind when contributing. ## Licence The library is published under the 'DPTechnics 5 clause' license. This is essentially the same as the `BSD-3-Clause` license with the addition that binaries of which the source code is not open should run on a Walter board from DPTechnics bv.
