Biohead Posted March 23, 2016 Share Posted March 23, 2016 Does Apple list the proper technical specifications of their iPads anywhere? I'm looking for something that categorically states what the power class is of their devices but I can't find it. The closest I've come is the user manual, which says under the Bluetooth section that it has a range of about 33ft (10m). Now that suggests it's Class 2, but I need something which states it in black and white.

#Michael Posted March 24, 2016 Share Posted March 24, 2016 Which iPad? iPad pro: BT 4.2 iPad Air 2: BT 4.2 iPad Air: BT 4 iPad Mini 4: BT 4.2 iPad mini 3: BT 4 iPad Mini 2: BT 4 iPad Mini: BT 4 Now, BT 4 or LE BT, is still generally limited to within 30-50 feet.

Biohead Posted March 28, 2016 Author Share Posted March 28, 2016 No, I'm referring to the Power Class, not the version. So Class 1 devices transmit at 100mW: Class 2 at 10mW; Class 3 at 1mW. Typical ranges are 100m/10m/1m. Almost all mobile devices are Class 2, and the ipad user manual states 33ft range (10m), but I need something to prove that.

zhangm Supervisor Posted March 28, 2016 Supervisor Share Posted March 28, 2016 You can find it, takes a bit of searching. Here's one example: Look up the device teardown on iFixit. Find the device used for bluetooth. In the case of the iPad 4, the Bluetooth device is a Broadcom BCM4334. https://www.ifixit.com/Teardown/iPad+4+Wi-Fi+Teardown/11462 Hop over to bluetooth.org and run a search for the module. https://www.bluetooth.org/tpg/listings.cfm We pull up a match to BCM4334 here: https://www.bluetooth.org/tpg/QLI_viewQDL.cfm?qid=18552 Show the ICS details and see what's checked off. In the iPad 4, the BT module is class 1.

FYI, if you have Apple Watch and iPhone, then it could be around 350 ft between those devices.
