How to disable BLE LL channel selection algorithm #2 on FRDM-KW38 platform

[Jokerufo]

how to disable 'gLeChannelSelAlg2_c' bit in 'LeSupportedFeatures_t' which pass to application layer during BLE stack initalized.

1)i have searched all the SDK of KW38, it's seem that no api to disable gLeChannelSelAlg2_c in  'supportedFeatures'.

2)i refence frdmkw38_wireless_uart_bm as example

3）i want to only use channel hopping algortham #1

is there any method to update 'supportedFeatures' supported by controller stack???

Hello @Jokerufo

Hope you are doing well.

Could you please provide more details on your inquiry? Which demo application from KW38 SDK are you using as base for your development? What is the purpose of this requirement in your project?

Please, take look at the BLE Application Developer's Guide and BLE Demo Applications User's Guide (included in KW38 SDK documentation folder > docs > wireless > Bluetooth). These documents describe the prerequisites and the initialization of the Bluetooth Low Energy Host Stack, as well as a detailed explanation of the most commonly used APIs and code examples.

Regards,
Eduardo.
