The purpose of this repository is to make performance tests on how different setups (pure C calls, Go + Cgo calls, ...) perform to call the Semtech lora_gateway HAL. The calls are configured for a Multitech Conduit with FTDI link, on the Europe LoRaWAN frequency plans.
It will contain 3 different tests:
- Pure C call
- Go + Cgo call (located in the go folder)
- Rust call
The easiest way to generate the benchmark binaries is to use GitLab CI, which works just like Travis CI if you've ever used it. Create your fork of the repo on GitLab, enable CI for this repo, enable a Runner, then push the repo to GitLab - your Runner will execute the GitLab CI file and generate the binaries for you.
The first benchmark consists of:
- Configuration of the SX1301 chip: board configuration, channel configuration... with a hardcoded configuration.
- Starting retrieving uplinks by calling
lgw_receive100 000 times.
We went for this setup because the tests were made in an environment where LoRa packets were emitted by a node, every ~5-10 seconds - going for 100 000 times would give us the right balance.
