Hello, I have just purchased the new Raspberry Pi Pico W and I'm trying to install the 'secrets' module on it using Thonny. Unfortunately, whenever I try to install it I get the following error message: "minipip returned with error code 1". I've had this problem before trying to install modules, but...

I doubt I need to say this, but I have no idea. Well done for spotting a fault though!

Just tried it with Circuitpython + pullup resistors and it's working perfectly. Thank you so much for all of the help!

I've tried it with various different frequencies (including 100Hz, 400Hz, 4kHz, and 400kHz) and it's still not working. I'm going to try it with CircuitPython, but Thonny now won't let me install any libraries. It just says: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expir...

I tried setting the frequency to 4000 but still no luck. Thanks for the suggestion though Nitrosfpv :) Roberthh, I've connected three pullup resistors in series to reach a total of 1.27kΩ (330Ω, 470Ω, 470Ω). The Pico is still failing to detect the BNO055. I'm using wires which are around 20 cm long....

Ok, I think mine does, it is a breakout board and appears to have a lot of functions. Any idea why it isn't working with the basic setup then? I've tried changing the frequency as you said.

I still don't quite understand what you mean when you say "between the SDA/SCL and 3.3V". This is my current setup: - Pico GP0 to BNO055 SDA - Pico GP1 to BNO055 SCL - Pico 3v3(out) to BNO055 Vin - Pico GND to BNO055 GND I have tried putting normal resistors into the SDA and SCL lines between the Pi...

I've tried connecting the gyro to a greater power supply, ~5V. I've also changed the wiring to see if that makes a difference, and still no luck.

My SDA and SCL aren't connected to a 3.3v pin. Only the power is. Have you got any idea why it might have changed, because it was working ok before without any change to the wiring.

I've put resistors in the scl and sda lines. Is that what you mean? I've also tried lowering the frequency, but that hasn't worked either.
