@jmarcelino Yeah, all up to date to the latest firmware. We are working them pretty hard, I guess they are reaching somewhere into the 45+ degrees C

hi @sprasad, So you're interfacing orientation sensor directly with GPY, right? You could control RST pin of GPY, or control Vin(3.5V-5.5V) from your powering scheme.

@sprasad said in GPy with BNO055 - I2C bus error: I2C(0, I2C.MASTER, baudrate=1000, pins=(Pin.exp_board.G15, Pin.exp_board.G16)) > ``` Expansion board G15 and G16 are P8 and P9. P8 is the SD_Data, but You don't use the SD card, the P9 on expansion board is the "led" pin. Try removing the led jumper "enable led signal" on expansion board to disable it.

Thanks @seb and @jmarcelino! Don't get exactly the same figures, but we're definitely in the same ballpark. I'll set this aside for now as I don't quite have the time and it was just a "nice to have" feature, but I suppose this should be investigated further at some point, as the sensor itself should only use 50 µA, not over 300, and it renders the wake-on-accelerometer feature a lot less useful. A few things that could be explored: it could be that keeping the accelerometer powered on means that all the other sensors are powered on as well and it is them using the rest of the current it could be the fact that the accelerometer INT pins are set to open drain it could be the powered down ESP32 (which looks like it's connected to ground when powered down) sinking current coming from a pull-up somewhere or it could be that the data sheet is just plain wrong :-)

@meirssv you can save this info to sd card, flash or nvs

@crumble thanks for your tips and enthusiasm. I'll keep you posted as I progress on the project, but time is scarse so don't hold your breath :-) You're not the first to bring to my attention the "good diffusor" issue.

Hi @Xykon , Thanks for reply, that works for the PySense update! The Battery I am using is a 3.7v 2000mAh. Thanks Michael

@bucknall : @chrisi runned into one of your documentation errors: https://docs.pycom.io/pycom_esp32/pycom_esp32/tutorial/includes/pytrack-examples.html#axis-accelerometer you might adapt the example as mentioned above.

@asaph I've tried it out and it works fantastically 🎉 Thanks @Daniel!

@Jiemde This is correct! They use the same sleep method as the deep sleep shield to control the devices sleep. I.e. setup_sleep() + go_to_sleep().

@Lokefar I'm happy to help with clean up and testing your code.
