Hi. I am looking at BLE5 Long Range applications, and would like to know the status of support for this in bluez and relevant kernel modules. Scanning the mailing list revealed some patches at least acknowledging the existence of coded PHY, but that was about it. BLE5 has two "long range" bitrates, at 125 and 500 kbps. (AKA BLE5 Coded PHY). As I understand it, selecting the PHY Coded rate can be undertaken by the bluetooth controller itself, or be controlled/requested by the host. Support for these rates appears to be available in controllers based on Nordic Semiconductors' nRF52840, Texas Instruments' CC2640R2F and SiLabs EFR32xG13. (Development/beta SDK/firmware may be required?). At least the first to exist as USB dongle implementations. Is anyone successfully playing with this under Linux? Are required bits for host control of PHY rate upstream? To what extent is support in the HCIBTUSB kernel driver required for this functionality? Thanks, Dag B
