Hi,

Since these are external components, there is not much we can help you with in regards to issues with writing. You should check the datasheet of the devices and make sure you follow the manufacturer's recommendations when it comes to interfacing the devices and checking return/status codes. Also, make sure that the commands you send from the nRF on SPI are correct.

Best regards,
Jørgen
