CoAP Limitations

Requests per device​

Golioth servers enforce the following limit on CoAP requests:

  • 20 requests per second per device

When passing frequent readings from a single device to Golioth (greater than 1 Hz) we recommend sending in batches. As noted for the LightDB Stream service, your device can add timestamps to data packets by using t, ts, or time as the key. The Golioth LightDB Stream service will use the timestamp for the database entry instead of the time received.

Payload length​

We recommend that you limit your payload length to 1024 bytes. The expected result of sending larger payloads is IP fragmentation which may result in unwanted retransmissions.
