A number of you have encountered a bug where the Spark Core will not hold a persistent connection to the Cloud, and does not successfully attempt to re-connect to the Cloud. Here are a few threads on the topic:
NOTE: This is a different issue from an unresponsive Core that still claims to be connected (https://community.spark.io/t/known-issue-long-delays-or-blocking-code-kills-the-connection-to-the-cloud/950). We are separately working on that issue, as noted in the linked thread.
This is a top priority issue and our lead embedded developer is still on vacation. So we’re offering it up to the community: who wants to take a stab?
There seem to be two separate issues at hand:
- A Core with a solid, reliable internet connection will at some point disconnect from the Cloud, often after hours of being successfully connected.
- While the Core should automatically re-connect, it does not do so, and instead stays in a persistent state of “flashing cyan” until it is manually reset. (NOTE: This is in contrast with disconnects that happen for other reasons; for instance, when we re-boot the Cloud, Cores automatically re-connect without issue).
These issues probably stem from our implementation of the CC3000 host driver.
We are issuing the following bug bounty:
- If you (1) make an improvement to our firmware to fix the above issues and kill the ‘cyan flash of death’ (2) send your improvements in as a pull request on Github, and (3) your pull request is accepted by the team, we will send you a $100 credit for Spark stuff (Cores, accessories, or kits), plus a Spark T-shirt to share your love!
- If multiple pull requests are sent, the first that we accept will get the bounty. If we accept other pull requests for incremental improvements, they will receive a free Spark Core, up to a limit of 5 pull requests. Only one bounty per person.
- If you make any other unrelated improvements to our firmware that specifically relate to improving reliability of the connection to the Cloud that we accept as a pull request (same 3-step process as above), we will also send a free Spark Core, up to a limit of 5. Only one bounty per person.
NOTE: You will need to sign our Contributor License Agreement for us to accept your pull requests.
