Sorry for the delay, the Cortex-M33 was a new platform for us. Could you please let us know if the attached release works for you? ... View more

Assuming BMI270's auxiliary interface configuration, bmm150_read/write functions, timings/delays and data read-out are all correct, this short code snippet seems valid. Joining this other comment, BMM150 is actually quite robust against magnetization and magnetic shocks, therefore I would also make sure that the magnetic environment around the sensor is also relatively stable and clean. ...

Since there are different part numbers mentioned, I will go with some generic guidelines. A good starting point would be the HSMI (Handling, Soldering & Mounting Instructions) manual of the product you are interested in (e.g. see BME280's HSMI manual here, you can find it from the product's page or Downloads page on our website). Our environmental sensors are protected by a metallic lid, but features an opening hole to the environment. Water, dust, vapor phase soldering, cleaning agents, etc. shall not enter this hole and get on the sensor elements. If needed, the hole of the device could be protected against contamination during such processes by some silicone-free protective layer (e.g. kapton tape). Using a protective vent/membrane in the field is common practice (often achieved at the casing/housing level) and should not significantly impact the measurements. Please avoid total or partial covering of the sensor by any protective material. For the best performance, integration is key and it is therefore important to consider the HSMI's guidelines (position of the sensor, thermal (de)coupling, dead volume, air flow, etc.). ...

Unfortunately there was a bit of confusion between the platform in the title and in core of the message, and it seems we would need a little more time to generate the requested release. We will try to get back to you in the beginning of the next week. ... View more

Would you be able to share any further details about your setup? For example any of the following could help: your schematic (unless you are using our official Shuttle Board(s)?), code snippets, timing information, logic trace, etc. ... View more
