pouch is a non-IP protocol for communication between devices and cloud services, typically through one or more gateways.

The pouch repository is a Zephyr module and can be included in any Zephyr project by adding the following to the project's west.yml file.

- name: pouch
  path: modules/lib/pouch
  revision: main
  url: https://github.com/golioth/pouch.git

pouch depends on the zcbor Python tooling. Use the following command to install it in your environment.

pip install -r modules/lib/pouch/requirements.txt

pouch messages ("pouches") are delivered over a transport. Transport implementations can be found in the src/transport directory. Currently, implementations for the following transports are provided in this repository.

The ble_gatt transport delivers pouches over Bluetooth Low Energy (BLE) Generic Attribute (GATT) Profile. An example of using pouch with the ble_gatt transport can be found in the examples/ble_gatt directory.

The golioth_sdk implements Golioth device management, data routing, and application services over pouch. The table below indicates the current status of support for each device-facing service.
