Myriota

Myriota provides global IoT connectivity through its satellite network, making it ideal for remote and low-power deployments.

Blynk offers a seamless integration with Myriota to decode uplinks and visualize data from your satellite-connected devices — no custom backend required.

Setting Up the Integration

1. Create a Destination in Myriota

To send uplink data from Myriota to Blynk, start by creating a destination:

1. Open Blynk Console and go to Developer Zone > Integrations > Myriota.

2. Copy the HTTP Destination URL provided.

3. Open your Myriota Device Manager, go to Destinations.

4. Click Create New Destination and paste the copied URL.

5. Click Create to save.

Note: If you update the HTTP Destination URL in Blynk, remember to update it in your Myriota destination settings.

2. Write a JavaScript Decoder Function

You’ll need to provide a JavaScript uplink decoder function in Blynk to parse the raw binary payloads sent by your Myriota device.

The decoder should return an object with keys matching your Blynk datastream names.

Sample Uplink Decoder for Myriota Devices in Blynk:

function decode(bytes) {
  const sequenceNumber = bytes.readUint8();
  const time = bytes.readUint32LE();
  const latitude = bytes.readInt32LE() * 1e-07;
  const longitude = bytes.readInt32LE() * 1e-07;
  const temperature = bytes.readInt16LE() * 0.01;
  const current = bytes.readUint16LE() * 0.001;

  const date = new Date(time * 1000);
  const dateStr = date.toUTCString();

  return {
    'Sequence Number': sequenceNumber,
    'Time': dateStr,
    'Location': [longitude, latitude],
    'Temperature': temperature,
    'Current': current
  };
}

Byte Reader Methods

The bytes object supports the following built-in methods:

Integer Readers

• readUint8(), readInt8()

• readUint16(), readInt16()

• readUint32(), readInt32()

• readUint64(), readInt64()

Floating Point Readers

• readFloat16(), readFloat32(), readFloat64()

Little Endian Variants

• readUint16LE(), readInt16LE()

• readUint32LE(), readInt32LE()

• readUint64LE(), readInt64LE()

• readFloat16LE(), readFloat32LE(), readFloat64LE()

Offset-Based Readers

• getUint8(offset), getInt8(offset)

• getUint16(offset), getInt16(offset)

• getUint32(offset), getInt32(offset)

• getUint64(offset), getInt64(offset)

• getFloat16(offset), getFloat32(offset), getFloat64(offset)

• LE (little-endian) variants are available for all

Other Utilities

• bytes[index]: Access a byte by index

• bytes.length: Total number of bytes

• bytes.offset: Current read offset

Tips

• Match your decoder logic with your device’s encoding format

• Return an object with keys matching Blynk datastream names

• Decoder script must be under 5,000 characters

3. Connect a Template

To receive and display parsed data in Blynk:

1. In the Myriota Integration window in Blynk Console, click Add Template

2. Select a template for visualization

3. Paste your uplink decoder function

4. Click Save

Sending Data to Blynk

Once the integration and template are configured, you can create a device to start receiving and displaying satellite data:

1. In Blynk Console, go to the Devices section

2. Click New Device

3. Choose From Template

4. Select the same template used in your Myriota integration

5. Click Create

6. Click the info icon next to the new device

7. In the Terminal ID field, enter the Myriota Device ID from your device manager.

This links incoming payloads to the correct device instance in Blynk.

Troubleshooting

If data isn’t coming through:

1. Open the Myriota Integration page in Blynk Console

2. Click Error Logs on the integration card to view recent errors
