I notice that the pins you've selected for SPI in your application are recommended to use at standard drive/low frequencies only. This is because they are located close to the radio, and might cause noise on the radio if you run them at high frequencies.

Please follow the Pin assignments in the nRF52840 datasheet for which pins have restricted usages or not. Also, please note that the SPIM3 instance is the only one supporting higher speeds than 8MHz.

Best regards,

Yes, the nrf52 will be transmitting image data over BLE to app. in app its converting image data if i am using arducam camera, so no issue from app side. Issue is i am not getting complete data in spi may be due to high frequency 32M,so i started using spim(for high frequency) which is in nrf example, but in that its not reading any spi data only. i have done proper configuration and connection is proper.

Is the nRF52 supposed to transmit this forwarded image data over BLE to another device or to output the image on a screen or similar serially? You might need to convert it back into image data, but first try to find out where in this line it is converted into hex format, as it's pretty clear that is what you're printing out now.

Hi, Thanks for your reply.

I am using nrf SDK version 16.0. Yeah I have checked nRF52 BLE image transfer demo and but that is all related to arducam. HX6538 have SDK which is already capturing image from camera through i2c and then sending to wiseeye which i ma reading through SPI pin. But that data is not coming properly, as not in image format.on 16.0. Yeah I have checked nRF52 BLE image transfer demo and but that is all related to arducam.

So, what SDK version are you using for development here? Have you checked out the nRF52 BLE image transfer demo that shows how a camera is set up and used to communicate with an Android app here? There the camera is set up in ArduCAM and ArducamMini .c and .h files that you can probably use for reference with your Wiseeye referring to the camera's datasheet.

Best regards,

So one thing i forgot to mention its Himax Wiseeye module and i am guessing its HM01B0 camera.
