Hello, we have a working board with the BNO085, but unfortunately the last time we ordered the BNO085 was not available, so we mounted the BNO055. We want to communicate via Uart, because the SPI is not available on the BNO055. But unfortunately there is no sign/output from the BNO055, even the TX line stays low. PS1 is high, PS0 is low. When we start the IC in bootloader mode, the TX line goes high. The pins 15 and 16 are open. In the old datasheet they are tied to GND, in the new one they are not connected. Do you have any idea ? Is there a way to upgrade the FW ? Thanks Andi
