Hi, In Bluetooth LE you can read and set Channel Map from/to the controller. Nimble has it implemented and application can make use of it by including ble_hs_hci.h file.
Here are the functions you are looking for: int ble_hs_hci_set_chan_class(const uint8_t *chan_map) int ble_hs_hci_read_chan_map(uint16_t conn_handle, uint8_t *out_chan_map); Best Łukasz On Tue, 20 Aug 2019 at 20:02, Elivander Judas Tadeu Pereira < elivan...@mtel.inatel.br> wrote: > Greetings, > > My name is Elivander J.
