Important notices

Limitations and known issues
of the SEEDlink server in dig v1.2
Details
Backfill of a historical segment of samples is not supported - i.e. the SEEDLink server in dig v1.2 only supports live streaming of samples In addition to SEEDLink DATA commands, SEEDLink clients can ask for live streaming of samples using SEEDLink TIME commands with zero or one arguments.

However, because SEEDLink TIME commands with two arguments are used to ask for a historical segment of samples, the second argument of these SEEDLink TIME commands are always ignored by the SEEDLink server in dig v1.2. In other words, SEEDLink TIME commands with two arguments are always treated as if they were SEEDLink TIME commands with only one argument.
Dial-up mode is not supported. SeedLink FETCH commands are always rejected. The SeedLink server of dig v1.2 will only operate in “real-time” mode.
The ‘!’ negation character in stream selectors is not supported. Negative stream selectors are always rejected. The SEEDLink server in dig v1.2 only accepts positive stream selectors.
Leap seconds are not supported. (There are currently no pending leap-seconds.)
SeedLink handshaking in uni-station mode is not supported. IRIS states that “almost all connections are negotiated as multi-station, even if only a single station is requested; uni-station mode, for most publicly accessible servers is deprecated.” (Iris SeedLink Overview).
Latency problems. The seedlink_samples_streamer thread polls for new samples instead of being event-driven. This software pattern is subobtimal, especially with regards to latency, but it was much quicker to implement as an initial version.

Change log

2019-11-25 : release 2.0-8154
This is a major new release with significant new features, including:

Many system performance and stability enhancements are also included, as well as a number of bug-fixes.

This release includes an upgrade of the boot-loader so there is a small chance of serious problems if the upgrade process is interrupted for any reason (although significant precautions have been taken to minimise this risk). It is recommended that the upgrade only be performed when the network and power-supply are both known to be stable.

For this reason, the upgrade dialogue in the Firmware Update section of Discovery will offer the choice of whether to accept this upgrade or not. Users wishing only to upgrade to the latest release 1 build can, therefore, avoid this risk if desired.
