![]() The "Spherical Camera" and third party "wired" devices will shortly be released. Take a look at our GoPro HERO5 Interfaces Futures We've taken a look at the protocols which exist in the GoPro HERO5. According to Abe Kislevitz, after 8 hours BLE shuts off and the battery only drains 2%. As a note, most BLE devices last a couple years with a coin cell battery. Gone is the blinking blue LED, because honestly it doesn't matter anymore. This low power connection allows your phone and controllers such as the REMO (Code named Sniper) to power on the camera without the drain of Wifi. Luckily, BLE takes almost no energy but the GoPro will shut down BLE after 8 hours. You probably didn't realize, but BLE (Bluetooh low energy) stays on after the camera has been powered off. Calibration is done via the pogo pins and is not accessible without a firmware mod. Bad Pixels, Vignette, Gyro, Audio, White Balance, and Communication. Man there is a lot of calibration done on these things at the factory. It's always fun to uncover the hardware code names.

Kirkwood (GoPro KARMA) uses MTP over USB to control the camera once the PD determines the Kirkwood via the Sentinel is inserted. The USB-C debug accessory is not enabled so communication to the RTOS or Linux needs to be done slyly. Once the device is determined, it can enable I2C, SPI, USB, I2S etc. The "HEROBUS" is now over USB-C via the PD (CC1:2) channel. I don't have any HERO5 third party batteries to test out, but it appears this test is done within the Atmel MCU and probably to a ATSHA204 via 1-wire. UPDATE - GoPro HERO5 BLACK version 1.55 does test for authentic batteries and locks customer's out if the identify friend or foe is incorrect. Right now I believe it's just a, "are you there?" Just FYI the 4 lines leading up to the battery are BATT+, BATT-, Thermistor, one-wire comm. 1-Wire communication is going on between these two, but we haven't looked into the protocol yet. Speaking of which, the battery is also polled for an authentication response. That's a lot of inventory they have to throw away and sure they are not happy. left a carrot out on the third party batteries then swiped it away with the v.1.55 firmware release. Sure the Chinese are on it right now after GoPro Inc. When a datasheet warns this much, you know there is a hole. In fact, if a SWD probe is connected, this BOD test is disabled so it may be possible to boot the MCU without code protection. The Atmel D21 datasheet specifically warns of VDDANA BOD-(brown out detect) being on and expect it possible to glitch the fetching of the code protect bits during power on reset. Update None-the-less, circumvention is possible, but will take some work. ![]() It appears Atmel's appnote was followed so perhaps they used the default keys of C0DE or GoProGoPro. The MCU's bootloader and "app" are encrypted and they've code protected the device. The first devices that use the new HEROBUS are GoPro Karma, a Spherical Camera solution, a display port dongle for the Session, and the Gantry (Pro 3.5 mic adapter). We've done a through-all analysis on this encryption, but will keep it internally. Once authorized, D-/D+ pairs, become their appropriate functionality. ![]() When an accessory is detected by communications over CC1, authentication is done to a ATSHA204A over i2c on the TX+/TX- pins. It also coordinates all the USB-C PD (power delivery controller) and USBC pin muxing. The surprise is the Atmel SAM D21E16 part (Australia MCU) which is used for Identify Friend or Foe Challenges and to offload some of the smarts talking to HEROBUS (GCCB Protocol) devices. GoPro HERO5 GNSS module with antenna on back side Encryption / DRM The GPS antenna is located above the lens. There are 3 mics with waterproof channels, and a speaker. The face is on there tight and the heatsink / mounting face appears to be made out of magnesium. Ambarella A9se7 Processor (800mhz), 4Gb NAND, 8Gb of DDR3 (600mhz), Qualcomm for wireless, ublox for GPS, and AMS again for power monitoring and charging. The hardware for the most part is understandable. On accessories to ensure authentic (i2c).

Well, it lasted a whole week, but I had to pop the hood on the new GoPro HERO5 (Australia - Streaky MP) and see what makes it tick. Let's start with the hardware
