  • @Matt said: @Timo_at_Myontec the low frequency clock on MMR is 250ppm typical, 500ppm worst case. It is trimmed against the high frequency crystal, and retrimmed if the temperature changes more than 2 degrees. This only applies if you are using t…
  • Hello, I read this example code: https://mbientlab.com/tutorials/LJS.html#bluetooth-dongles. Sorry, how I can get the 'hciconfig' istance? Thank you
  • Ok, I resume the current situation. 1 - Two MMR boards are blocked in this state: "The board becomes visible to the bluetooth adapter only when I press the button on the board". Moreover, I can't connect to them with Android App and python code. …
  • Sorry, but if the board is invisible now from PI, my Android smartphone and my Linux PC, why do you think that it can be visible from an Apple smartphone?. The bluetooth adapter of this type of smartphone has special powers!! However, at the moment …
  • 25Hz is already the lowest sampling frequency for BMI160 (https://mbientlab.com/documents/metawear/cpp/0/gyro__bmi160_8h.html#ad345f6ab63af332180c7c66c0fc830fe) I run some tests with one board and the RaspberryPI integrated bluetooth, the total t…
  • Yes! I still have a blocking problem with two boards. The current behavior is that when I press the white button on the board, it become visible. But, then, I can't connect to it! I tried to connect from AndroidApp and two different PCs, but nothin…
  • Thank you four your answer. Perfect, I will try another architecture with also the new BLE dongle. Sorry, but, I don't understand why in the last test that I run with only one baord I had these results: _acc_samples : 1467 [(1500-1467)/1500]*100…
  • Sorry, but you understand my words? * I've already tried the soft reset ((https://mbientlab.com/troubleshooting/), but nothing. Could you explain me with more details this procedure? I've some doubts about it: I need to press the button for a m…
  • I replaced the standard command with these: _mbl_mw_acc_get_packed_acceleration_data_signal _mbl_mw_gyro_bmi160_get_packed_rotation_data_signal _mbl_mw_mag_bmm150_get_packed_b_field_data_signal NOTHING is changed. The performance when I used on…
  • * I used 'hciconfig hci0 reset' command, but it doesn't resolve the issue. * When I used 'sudo hcitool -i hci0 lescan --passive' command I have always no issues. I tried to apply to the first (A) and second (B) board s new advertise interval. I…
  • Similar issue with RaspberryPI. Read: https://mbientlab.com/community/discussion/3397/packets-lost-streaming-data-from-multiple-boards#latest
  • The second test executed after the first explained in the post above then, the thirst test. Now I am blocked! Nothing is changed between the tests, same code, same hardware and same distance between Metamotion boards and RaspberryPi (less tha…
  • I read this suggestion ("Use iOS") a lot of times in this forum. If I don't have a iOS device and I cannot retrieve it, It is a my own problem or there is another good way to upload the firmware on your boards? Thank you.
  • I didn't forget anything, there is a compilation problem on Windows. Anyway I resolved the problem with Ubuntu 16.04 OS and python 2.7. Now I can run the examples scripts. Only one issue in the connection phase, the scripts are successful executed a…
  • I get the same message ("Firmware update failed (reason = No value for bootloader)") and the update proccess does not start. Device: Xiaomi Redmi 4 OS: Android 6.0.1
  • Hello Akah, Like you I need to connect to multiple boards (10 MetamotionR boards) and get data from them by my PC. Do you have some example code that you can share with me? I don't find multi_device.py script, where is it? Some questions about b…
  • Anyway, you stopped supporting, but why you also stopped sharing these example scripts?. Some oher companies let the users download scripts (with a disclaimer) althought they are not supported. I don't understand what is the problem, they are simple…
