Hi, I got a BHI260AP on a Shuttle Board 3.0 and an Application board 3.0. I modified the quaternion.c example to read additional virtual sensors from the board (accel, accel_calib, gyro, gyro_calib, ...). I created several callback functions that push the sensor data to arrays, that I then want to write to *.csv files in the end. However, as soon as I add >2 virtual sensors with a sampling rate of 200Hz the FIFO starts to overflow. According to this document (https://www.bosch-sensortec.com/media/boschsensortec/downloads/application_notes_1/bst-bhi260ab-an002.pdf) I should have "plenty" of FIFO space available (Figure 3 -> 240KB/2?). If I calculate the amount of data (let's say 4 virtual sensors, 200Hz each, 3*16bit) I would arrive at 4.8KB / second. That should not exhaust the FIFO right? I tried flushing the FIFO in the main loop, but that made no difference? I also increased  WORK_BUFFER_SIZE from 2048 to 8192 but that did not make a difference either.         bhy2_flush_fifo ( RAW_ACC_ID , & bhy2 );         bhy2_flush_fifo ( CALIB_ACC_ID , & bhy2 );         bhy2_flush_fifo ( RAW_GYR_ID , & bhy2 );         bhy2_flush_fifo ( CALIB_GYR_ID , & bhy2 );         if ( get_interrupt_status ())         {             /* Data from the FIFO is read and the relevant callbacks if registered are called */             rslt = bhy2_get_and_process_fifo ( work_buffer , WORK_BUFFER_SIZE , & bhy2 );             print_api_error ( rslt , & bhy2 );                     }   I also checked the timestamps differences. If the FIFO overflows there are some drops of course in the sampling rate, because data goes missing.   What am I doing wrong? Is it not possible to get the data from 4 sensors at the time on a PC as host and save the data?    Regards Steffen ... View more

Hi guys,  I am trying to evaluate the BHI160B for our application (we wanted to use BHI260, but they were not available atm). Therefore, we bought the Shuttle board and application board 3.0. I am trying to understand the documentation, but information is quite scattered. I am facing two major challenges: 1. When I use the development desktop 2.0, I can connect the board and download the BMI160_BMM150 firmware to it. Then under virtual sensors I am setting a sample rate for Accelerometer, Gyroscope and Magnetometer and enable raw data output and press write. As soon as I click Start streaming the sensor data arrives, but after 1-2 seconds it just stops without error or anything. Same for Orientation. In addition, the sampling rates that I set are not the same as shown in the "physical sensor working status" tab. 2. Second I tried to get the sensor talking over command line, so I am using Coines under Windows. Building the BMI160 example works, however when I execute it I  am getting the error "Warning invalid sensor shuttle,This application will not support this sensor".  So I tried  the BMM150 example. Same error. Then I found this repo https://github.com/BoschSensortec/BHy1_driver_and_MCU_solution however, there are no makefiles provided for the examples. At the moment I am a bit lost, could you please provide me with some guidelines how to simply get the sensor data from BHI160B shuttle board 3.0 on a Application board 3.0 with a C or a Python example?
