nRF52833 Coded PHY

[Louw]

Good day

I am currently developing a system using the nRF52833. A nRF peripheral device needs to be connected to both a mobile app and a nRF central device. The software on the peripheral currently is able to connect to both the mobile app and central, using 1MBs PHY. I need the peripheral device to be able to connect to the mobile app using 1MBs PHY and to the central device using Coded PHY.

I have been struggling with this for a while now and any help would be appreciated. I have read through the forums and any examples I was able to find, but I am still unable to resolve the issue.

Could you please provide me with a list of things to change/add on the Nordic side of the project, specifically for the nRF52833.

Kind regards

Details:
nRF52833 on a custom PCB
nRF5 SDK version 17.1.0
Soft devices s140-7.2.0 and s122-8.0.0
The software is adapted from the BLE UART examples in the SDK

Hi

Indeed, only advertising/scan initialization should be necessary to add Coded PHY. Most importantly are the following inits (in advertising):

init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

init.config.ble_adv_primary_phy       = BLE_GAP_PHY_CODED;

init.config.ble_adv_secondary_phy     = BLE_GAP_PHY_CODED;

init.config.ble_adv_extended_enabled  = true;

And these for scan_init: 

scan_params.filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL;

scan_params.scan_phys     = BLE_GAP_PHY_CODED;

scan_params.extended      = true;

Best regards,

Simon
