# Protobuf files for defining ota packet structures

ble_ota uses Google Protobuf for language, transport and architecture agnostic protocol communication. These proto files define the protocomm packet structure, separated across multiple fies:

• ota_send_file.proto - Defines OTA start, subsribe and send file commands and result structures. Note : These proto files are not automatically compiled during the build process.

# Compilation

Compilation requires protoc (Protobuf Compiler) and protoc-c (Protobuf C Compiler) installed. Since the generated files are to remain the same, as long as the proto files are not modified, therefore the generated files are already available under components/ble_ota/proto-c and components/ble_ota/python directories, and thus running cmake / make (and installing the Protobuf compilers) is optional.

If using cmake follow the below steps. If using make, jump to Step 2 directly.

## Step 1 (Only for cmake)

When using cmake, first create a build directory and call cmake from inside:

 mkdir build
 cd build
 cmake ..

## Step 2

Simply run make to generate the respective C and Python files. The newly created files will overwrite those under components/ble_ota/proto-c and components/ble_ota/python
