Inventory file

[langasg]

Hello
I am trying to install from Ansible but I don't know what the inventory structure should be like, could you give an example.
Thank you so much.

Hi there, it's been a few years since I interacted with this code, but I just dipped in to the repo.

I used the word "fridges" in ansible/deploy.yml, so I think this will work for your Ansible inventory local to the project directory:

inventory.yml

---
fridges:
  hosts:
    myfridge:

For that file to work, you will need an SSH config set up such that ssh myfridge lets you access the target device you want to deploy the code to.

Thanks johnelliott

I have managed to run ansible, making some modification to the vars file, so that it finds the armversion params, but I have not been able to compile it. I am trying to compile without using ansible with the command
"root@raspberrypi:~/alpicoold/cmd/alpicoold# /usr/bin/gmake build GOARM=7"

but I get errors:

github.com/johnelliott/alpicoold/cmd/alpicoold

My workflow was to build this on my laptop and load the built binary onto my raspberry pi. Are you trying to do that or build the program on the same device you are running it on?

I`m trying build program on the same device (Raspberry pi). But tomorrow, i will try to compile on my debian laptop.

I think I have managed to compile the application. but I see some warnings.

Another question has arisen, in the code I see several fields that I understand should be changed.

alpicoold/bluetooth.go: serviceUUID = "00001234-0000-1000-8000-00805f9b34fb"
alpicoold/bluetooth.go: writeableFridgeUUID = "00001235-0000-1000-8000-00805f9b34fb" // Writable
alpicoold/bluetooth.go: readeableFridgeUUID = "00001236-0000-1000-8000-00805f9b34fb" // Read Notify
alpicoold/bluetooth.go: descriptorUUID = "00002902-0000-1000-8000-00805f9b34fb"
alpicoold/bluetooth.go: dFilter.AddUUIDs(serviceUUID)
alpicoold/bluetooth.go: char, err := dev.GetCharByUUID(writeableFridgeUUID)
alpicoold/bluetooth.go: log.Debugf("Found writable UUID: %v", char.Properties.UUID)
alpicoold/bluetooth.go: notifChar, err := dev.GetCharByUUID(readeableFridgeUUID)
alpicoold/main.go: addrF = flag.String("fridgeaddr", "", "address of remote peripheral (MAC on Linux, UUID on OS X)")^C

Anything else I need to change? before compiling again.

Thank you so much.

I`m trying build program on the same device (Raspberry pi). But tomorrow, i will try to compile on my debian laptop.

The easiest thing may be to log into the pi, then go to the alpicoold directory and do a go build from there, that would skip the makefile and cross-compilation.

As for changing settings, you can use an env file and don't need to set any app config before building.

[langasg]

Thank you so much.
I have managed to compile the alpicoold folder, but now when I run it it seems that it detects my device but does not connect with it.

I also don't know how I can get the uuids and if I have to configure them somewhere.
