It’s actually possible to use the debugger on the NRF dev kits to flash/debug custom PCBs with NRF chips. So a separate (more expensive) JTAG debugger is in fact not required.

BLE has a privacy feature that enables MAC address rotation, but it isn't a requirement. Apple products and Android phones use the privacy feature, but other than that most product…

Apple devices all use a private resolvable Bluetooth address that changes every 15 minutes. That, along with a cryptographic payload, protect against this. Aside from Apple product…

Not sure I agree here. Most Bluetooth Low Energy devices (aside from Apple Devices and Android phones) don't make use the privacy feature and therefore their device address can be …

There’s no actual Bluetooth connection that happens here. The AirTag or other FindMy-enabled device is purely transmitting. The packets being transmitted are Bluetooth Low Energy a…

Private resolvable addresses are a BLE thing, but very few devices (aside from Apple products and Android phones) actually use them. It’s a shame, really, because most embedded BLE…

It’s a little bit better than that, in that only some nodes rebroadcast everything while you can have lower-power nodes be primarily in transmit mode. But yes, I think the spec cou…

The Bluetooth Mesh standard actually is based on a Bluetooth 4.0 feature set (basic advertising and scanning), so really any BLE device can support it. The problem is that the soft…

Easy to say, and I can’t know for sure exactly what factored impacted Broadcom’s decisions here, but I can tell you that chip manufacturers are under extreme pressure to keep costs…

Bluetooth has the Secure Simple Pairing (SSP) feature, and Bluetooth Low Energy has the LE Secure Connections feature, which both use Elliptic Curve Diffie-Hellman Key Exchange and…

No, iOS devices enable Bluetooth Low Energy advertising pretty much the entire time that Bluetooth is on. This is used for features such as handover and Airdrop (and now for contac…

SEEKING WORK AND SEEKING FREELANCER | San Diego, CA | Remote We are a small consulting and design services firm focused on Bluetooth and Bluetooth Low Energy (BLE) technology. We d…

Nordic provides some easy-to-use tools and examples for encrypting and signing firmware images when using a bootloader for in-field updates. I would expect that most products based…

I suspect that in this case the phone is using Bluetooth Low energy “passive scanning”. This means that the phone is listening for advertising devices (eg beacons) but never actual…

I don't know of any because I haven't tested too many, but LE Secure Connections has been around since the Bluetooth 4.2 spec, which was adopted in 2014. The feature is supported b…

Sadly, many BLE keyboards on the market today are still not using the LE Secure Connections feature during pairing. The LE legacy pairing algorithm does not use Elliptic Curve Diff…

That is correct. The vulnerability note clearly states that this only impacts "Bluetooth BR/EDR Core v5.1 and earlier". "BR/EDR" is the technical term for Classic Bluetooth; in oth…

I think the biggest misconception here is the belief that Bluetooth LE beacons are tracking phones. The beacons themselves operate as transmit-only and don’t receive any data and t…

It's true that only paying companies (associate membership or higher) can participate in working groups and contribute to the specifications, but once a specifications has been ado…

And this article doesn't even mention Bluetooth Mesh. Yes, it's still very new and yet to be deployed to the extent of Z-Wave and ZigBee, but with the ability to directly connect t…

With the CC26xx parts you can use a 32kHz RCOSC and get accurate enough timing for BTLE connections, so with the CC2652RB you should be able to have true "crystal-less" Bluetooth L…
