https://devzone.nordicsemi.com/f/nordic-q-a/22804/nrf51-to-nrf52-mpu-9250-problemHello everyone, We&#39;re currently in the process of porting our code from the NRF51 to the NRF52 (both without any softdevices). Everything compiles and seems to be working fine, except for one part, which is that the connected MPU-9250 is no longeren-USTelligent Community 13Thu, 15 Jun 2017 23:18:02 GMThttps://devzone.nordicsemi.com/thread/89642?ContentTypeID=1Thu, 15 Jun 2017 23:18:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2147acec-e2da-4df8-b9a6-b309ccfc7502rct42<p>I&#39;d also question whether the hardware.</p> <p>How are the boards being soldered? Is this fault systematic -- does the same problem occur on multiple hardware units? I&#39;d suggest to see if the problem occurs by using a development board and a MPU9250 breakout board (eBay, Sparkfun...) just to rule out an issue with the hardware. I know how tricky 0.5mm pitch QFN ICs are to DIY solder / reflow!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/89643?ContentTypeID=1Thu, 15 Jun 2017 09:20:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c0ea72da-a9f6-40e3-8649-fffef9f1ca14J&#248;rn<p>Have you physically moved (resoldered) the MPU from one board to another, or is it on a separate board and just connected via wires/connectors?</p><div style="clear:both;"></div>
