Unfortunately, Marc’s recuperation after his hospitalization wasn’t quite as straightforward or expedient as he’d hoped for. The good news is he’s back at work today, albeit part-time, and a sense of normalcy and normal service should return. Thanks for your patience and support.
Hi all, I generally I wouldn’t write about my personal life on our blog as there should be a line between your personal and professional life. However, I feel it appropriate to let everyone know that I was hospitalized on the morning of February 1-10th and only discharged this afternoon. I’m planning on taking Wednesday […]
Firmware Stability The fixes for working around silicon issues that Nordic provided initially showed some good results in that they removed the stability issues during extreme, rapid temperature change (freeze a Wimoto Climate to ~-15c, then bring it to ~+40c quickly). However, when we started to power profile the devices earlier this week, we found […]
Preliminary testing of the temperature/timing fix from Nordic was encouraging. We still need to power profile the changes, which we’ll do tomorrow.
Nordic Semiconductor were able to deliver two software workarounds this evening for the silicon issues that have been causing our temperature-related instability in the new firmware. The only downside is a small bump in power consumption, but not enough to really make a material difference and stability trumps an extra week or two of battery […]
We’ve been working with our Nordic Application Engineer over the weekend, although he was off yesterday as it was Martin Luther King day. He’s been somewhat able to recreate our problem in that he can cause some instability by using a hairdryer to rapidly change temperature — however, we generally do the opposite in our […]
Firmware Stability If you read our blog update about our time at Global EMC doing our EMC and safety testing, you may recall we’d noticed something strange: our new firmware seemed a little unstable (it stopped “broadcasting”). We’d thought it was a software bug and have spent a ungodly amount of effort trying to trace […]
