Bluetooth 5 | LE Coded Phy

[erdem.simsek]

Hi everyone,

As you know, bluetooth 5 is introduced and its coverage increases up to 200 meter with the help of the LE Coded Phy.
The difference between LE Coded Phy and standart LE Phy is that how many symbols you spend to code one data bit.
According to the Bluetooth specification, there are two type to encode the data which are 2 and 8 coding.

Here is the point that confuses my mind,

The LE Coded Phy property seems like a software trick to me because, there is no difference between sending data and sending coded data.
Instead of buying Bluetooth chip that supports Bluetooth 5 , can i use Bluetooth chips that support Bluetooth 4.2 to use LE Coded Phy.
Is it possible, if yes how can i do? if no what the physical layer changes on Bluetooth 5 ?

Thanks for your attention
Have a nice day

Hi,

As much as i learnt, The Coded LE PHY is not a software trick and there exist a specific hardware inside the Bluetooth chip to detect Coded LE messages. Because of that. it is not possible to use Bluetooth chips that does not support Bluetooth 5 specifications to send Coded LE Bluetooth messages.
