Connection Modes

IoTy supports 4 different ways to connect to your device.

• Serial. This is the preferred way, but only works on computers and not mobile devices (eg. phone and tablets).
• Bluetooth. This works on computers and Android devices, but not on iOS (eg. iPads).
• Internet. This works on all devices, but requires WiFi and an MQTT account.
• Access Point. This works on all devices, but requires the most steps when downloading programs to your device.

• Works on laptops and desktops running Chrome browser.
• Does not work on mobile devices.
• Only method that stays connected when the device is reset.

• Need access to an MQTT server (...you can use the public server provided by Hivemq).
• Needs to configure your device using another mode first (...to provide it with the network settings).

Configuring Network

1. Connect using one of the other modes.
2. Open the connection menu, and select "Configure Device Network".

To use Access Point mode, you must first download your program as a JSON package. Click "File", then "Save code to JSON package".

Connection Steps

1. Switch your device to access point mode by pressing reset, then hold the boot button until the Blue LED blinks rapidly.

1. On your computing device (eg. Computer, phone, tablet), open the WiFi menu and look for an access point with the name of your IoTy device (...name that you have selected when flashing firmware). Connect to that access point.
2. Upon connection, you will lose internet access. This is normal!
3. Click "App", then "Access point page".

1. In the access point page, look for the "Upload Code" section, select "Choose file", then select the JSON package you have downloaded earlier.
2. Click the "Upload" button. You should see a success message.
