nRF52840 BLE Coded PHY errata 3.15 and 3.24 - Does nRF Connect SDK have workarounds?

[wkpolara]

We're using the nRF52840 with Zephyr in the nRF Connect SDK.  Our current firmware build is using the SDK v2.3.0.

For some important BLE links we're using the Coded PHY (S8, 125kbps), and saw the following two related errata for this part (we're using Rev2 silicon):

https://infocenter.nordicsemi.com/pdf/nRF52840_Rev_2_Errata_v1.6.pdf

3.15 [172] RADIO: Bluetooth Long Range co-channel performance

3.24 [191] RADIO: High packet error rate in BLE Long Range mode

Both appear to have software workarounds.

Does the nRF Connect SDK v2.x.x have these workarounds in the Zephyr BLE Controller support for the nRF52840?

(i.e. are they in the controller stack or do they need to be implemented in user code?)

Hi,

nRF Connect SDK v2.3.0 inclues workarounds for both errata 172 and 191 when using the SoftDevice Controller and you do not need to do anything on your end to enable the workarounds. It is also handled for the Zephyr controller, though I would recomend that you use the SoftDevice Controller for other reasons (this is the only controller we recomend for production, and the only we qualify).

Great, thank you for the quick response!

Hello Einar Thorsrud 

Does that mean latest nRF Connect SDK supports LE Coded phy S8 in both RX and TX with 125kbps? We are looking for long range only.

Hi,

Yes, that is supported. Please make a new question if you have more questions about that.
