NimBLE library

[Elivander Judas Tadeu Pereira <el...@mtel.inatel.br>]

Greetings,

My name is Elivander J. T. Pereira and I'm an engineer from the telecommunications department of the National Institute of Telecommunications (INATEL - Brazil). I'm student of the Master's degree course in this College.

I'm working with Cognitive Radio and Spectrum Sensing, to evaluate some projects in cooperative spectrum sensing we are trying to implement a project through the AFH protocol from the Bluetooth stack. However, since we had difficult to find how to use the channel map information data from the controller layer. Is this information possible to be accessed from the NimBLE code by other applications? I started to look the library this week and my perception is that the AFH protocol is implemented on the HCI code, is this correct?

I appreciate any help, documentation or collaboration that can auxiliate us.

Thanks and regards!

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
