Hi The Nordic company referred me to your website so I may get my answer here. My question is that I need to implement my own channel mapping based on a different scenario. For example, in the list of bad channels and good channels which use RSSI or PER. I want to increase the BER for good channels in a certain time period. Another example can be rescheduling the channel list based on different timing or clustering. I was wondering if your stack could kindly provide me with a solution. Regards Ali |

Hi Ali,

This is available in controller only binary (sample/bluetooth/hci_uart), or you can add your own API that your application could use. For example, in the list of bad channels and goodWhat is PER? I want to increase the BER for good channelsCurrently, there is no software support to profiling BER in the stack. But, stack does use CRC check on reception to accept valid packets. You can use the received packet, Rx-ed channel and CRC status to profile. Grep for “crc_ok” in subsys/bluetooth/controller/ll_sw/ctrl.c. Interesting function is isr_rx_conn, both RSSI and CRC status are available in that function for use.
