Change BitRate 1Mbs 2Mbs 125Kbs

[novello]

There is an examples that show how to change from a 2Mb/s to a Coded 125Kb/s ?

May I change the bit rate of the comuniucation dinamicaly ?  For examples I see that with a 2Mb/s comunication is not so good ( The Master can't reach the Slave  )The Master   can try with a 125Kb/s comunication or increase the power ?

There is in ble a parameter that show me quality of the link ? (QoS)? 

There are some examples ?

Best Regards

Hi Novello,

Which SDK are you using? If using the nRF Connect SDK, you can look at this post. If you are using the nRF5 SDK you can call sd_ble_gap_phy_update() with the rx and tx PHYs set to BLE_GAP_PHY_CODED. With extended advertising you can also establish connections on coded phy (see this post).

There is in ble a parameter that show me quality of the link ? (QoS)? 

Not with the nRF5 SDK, but if you are using the nRF Connect SDK you can get information about that from the Bluetooth stack. This is used by the Quality of Service module.
