BLE initializes sometimes for 2 seconds and sometimes more than 10. Does anyone know the solution to this problem?

micropython 1.12 / esp-idf 4.0

I would like to implement the ability to update *.py files. Being connected via BLE (esp32) How to solve it most safely? create tmp.py -> add content -> check checksum -> delete old.py -> rename tmp.py to new.py ? are there better ways?

Hi, can possible read value from ADC2 pins (for gpio 2)?

im added in machine_adc.c

Code: Select all

{{&machine_adc_type}, GPIO_NUM_2, ADC2_CHANNEL_2},

and compile.

But it is probably not enough?
Thanks.

Thanks.

UPDATE: my mistake i meant esp32 sorry.

I mean to send/save the offsets. In order not to calibrate every time it is turned on.

Thanks for reply. I am using esp32. It also tests with the wires. As for them, I agree, IMU is awesome. But I'm having trouble calibrating after rebooting. I have mag offsets saved, after restart I send them to the device, but I don't know acc and gyro offsets so I don't give them, sometimes it's fi...

I think adding a timeout in i2c to 2000 helped, but is that a good solution and will it always work?

Hi, im use this driver: https://github.com/micropython-IMU/micropython-bno055/blob/master/bno055_base.py imu: https://www.dfrobot.com/product-1793.html It's ok, it's getting the data, but sometimes I get an error: File "libs/bno055_base.py", line 115, in _readn OSError: [Errno 110] ETIMEDOUT i2c: i2...

Thanks for reply.

Then it only sees the accelerometer data - the magnetometer does not.

Code: Select all

lsm303 = LSM303D(i2c)
print(lsm303.read())

((20, -204, 1069), (0, 0, 0))
