Debugging Harley LiveWire Bluetooth and iPhone Issues, Part 3

Look at what I found printed on the bottom of my LiveWire’s display unit: Two immediately interesting bits of information there -- a Harley-Davidson part number (70900801) and an FCC ID (SQGBT850). A bit of quick googling finds 70900801 is “INSTR,CLSTR,DIGITAL” (Instrument, Cluster, Digital). There’s even one on eBay right now. Google also turns up … Continue reading Debugging Harley LiveWire Bluetooth and iPhone Issues, Part 3

Setting Up iOS Bluetooth PacketLogger in Xcode

Edit (Oct 2, 2021): I later found a similar article on the Bluetooth SIG website iOS has two ways to see Bluetooth packets. One involves capturing a log file by triggering sysdiagnose and the other allows for live capture - you can see the announcement in “What’s New in Core Bluetooth” from WWDC 2019, especially … Continue reading Setting Up iOS Bluetooth PacketLogger in Xcode

Expanded mmWave Support for iPhone 13 5G

Apple's September 14th event introduced the new iPhone 13 and what caught my attention was a brief mention by Tim Cook of "new bands and antennas" for the iPhone 12 successor. Looking more closely at the specs shows that the iPhone 13 adds support for 26 GHz mmWave (n258), which builds on the 28 GHz … Continue reading Expanded mmWave Support for iPhone 13 5G

Most of these are very broad categories (for example, there are many types of Bluetooth with differing data rates) and I’ll be linking … Continue reading iPhone, iPad and Apple Watch Radio Subsystems (Index)

Debugging Harley LiveWire Bluetooth and iPhone Issues, Part 1

TLDR: If at first you don't connect, try, try and sometimes try again. I found my LiveWire would only connect to my phone roughly half the time, and waiting beyond 30 seconds for it to connect is unlikely to help. I'm determined to uncover as much as I can as to what is undermining the … Continue reading Debugging Harley LiveWire Bluetooth and iPhone Issues, Part 1

Swarm – Space Based IoT Connectivity has a Dev Kit Now

Now this is interesting. Was reminded about it on the IoT Podcast this morning. From IEEE: Swarm, a satellite start-up that uses CubeSats about the size of a grilled cheese sandwich to provide IoT coverage, has instead developed a satellite network specifically for IoT networks that would otherwise struggle to connect to the Internet. To … Continue reading Swarm – Space Based IoT Connectivity has a Dev Kit Now
