Go library for Broadlink RM devices

Go library for Broadlink RM devices

This library where created with work from the following pages:

• https://blog.ipsumdomus.com/broadlink-smart-home-devices-complete-protocol-hack-bc0b4b397af1
• https://github.com/mjg59/python-broadlink
• https://community.home-assistant.io/t/configuration-of-broadlink-ir-device-and-getting-the-right-ir-codes/48391

The library is designed to work with Broadlink RM Mini3 or similar devices. It can configure the WLan settings of the device and learn and send IR commands over the device.

In the root directory is a sample command line program "main.go" where you can see the usage of the library.

Usage question

Hi @waringer,
I'm trying to use the send command-line option using the code learned from -learn, and I'm getting a decoding error that it's not clear how to fix.

go run main.go -ip=192.168.1.84 -v -d -learned

I've also tried wrapping the code in single and double quotes with the same problem, am I just missing something stupid?

Thanks,

Panic: runtime error: slice bounds out of range [34:0]

Hey hey, thanks for your awesome go lib! I was able to setup my RM3 mini successfully, but when I start learning I get a Panic: runtime error. Any idea how to fix that?
