Application Crashes When Enabling Both 1M and Coded PHY in BLE Scan Init

[Nikunj089]

Hi,

I'm using nRF SDK 16 for my application on the nRF52840 custome board.When I set both parameters (i.e., support for coded PHY and 1M PHY) in the scan initialization function, my application hits a hard fault. However, if I configure and run scanning separately for each PHY, it works fine.

But I want my application to support scanning for both advertisement types (1M and Coded PHY) simultaneously.
Please suggest the correct steps to achieve this.

Thanks

Hi Nikunj Kumar,

What are the details of the hardfault? What are the code snippets and changes you made to enable those features. I strongly recommend you to use the latest SDK (nRF Connect SDK) while evaluating features.

The error code 0x7 returned by sd_ble_gap_scan_start corresponds to NRF_ERROR_INVALID_PARAM. Seems like you have zeroed out the init_scan struct and only initialized few variables in it. That seems wrong. This means that one or more of the parameters you are passing to the function are invalid. This error with this API has been discussed a lot on this forum, please try to read the forum to see if that helps, for example this one and this one.
