Hi Vincent, Thank you for your quick reply. I contact Bosch support using the link you shared. It seems, they are not very responsive. Probably takes couple weeks until they find my email 😄 Just have a quick question, As I understood, if I connect BOOT & RESET pins (BNO055) to MCU, I would be able to update the firmware via I2C later time Kind regards, Reza

Hi Vincent, I am also keen to upgrade my BNO055 via my own MCU. Can you please provide more information on how I can achieve that? I haven't burned the final PCB yet, so I am quite flexible to expose pins. thanks

Hello Robin, No, I am not using the BNO055 USB stick. I don't think if it's a good idea to use the BNO055 USB stick for upgrading the FW and then de-soldering the chip. Currently, I am using one of the common breakout boards for BNO055 to communicate with the sensor (and hopefully upgrading the FW) If that works I am gonna make a PCB that can operate the sensor as well as be able to upgrade the FW. So, do you know how should I connect the pins?

Hi, I am keen to update the firmware BNO055 sensors to the latest version using Bosch Development Desktop 2.0. I tried to set the sensor in UART mode and connect it to a PC using a UART to USB dongle, but the software failed to find the sensor. Is there anything more than Power, RX and TX pins required to be wired? Kind regards, Reza

Hello BSTRobin Thank you for your reply. Yes, that's true. for ACC_AM_THRES and ACC_NM_SET registers, I stick to the default values which are 0x14 and 0x0B respectively. Anyway, I receive the interrupts but the INT pin stays high even though INTR_STAT value is 0x00.
