nRF52832 zephyr based HCI beacon scan issue

[$pider]

Hi,

We are using nRF52832 based module on which we are using HCI over UART functionality with the help of Zephyr(v1.14.0) SDK to find the nearby beacons via Bluez stack(v5.50 - stable).

1. For this functionality, we continuously start & stop the LE based device discovery at around 10 seconds of intervals. After around 100 to 150 times of doing such activity continuously zephyr based nordic module Fail / Rejecting to any further commands of enabling/disabling scan request via hci_le_set_scan_enable() Bluez API. - So am I missing something here, or it was a known behavior of default zephyr HCI example configuration?

2. Also, to debug this problem we are unable to run RTT logs with HCI functionality in zephyr SDK, at a time anyone of the interface can be run but not both simultaneously. So, to do so which type of configuration is required so that JLink RTT logs will work with HCI interface?

Hi,

1) I have not seen this behavior before. What does hci_le_set_scan_enable() return ?

2) See this link. Try setting this in prj.conf,

CONFIG_UART_CONSOLE=n
CONFIG_RTT_CONSOLE=y
CONFIG_HAS_SEGGER_RTT=y
CONFIG_USE_SEGGER_RTT=y
