Hi,

[quote user=""]Thread Priority: We believe the PPP RX processing thread may be running at a priority too low to compete with other Application Core threads (like our BLE observer/Flash workqueue, which uses the system workqueue). What is the recommended priority for the PPP RX thread to prevent starvation?[/quote]

After thread has been started, it is possible to change its initial priority if this is needed. This is described in thread priority.

[quote user=""]Core Memory: Is it possible that the buffers are being depleted on the Network Core (Net Core) before they even reach the Application Core's memory management, and are there specific Kconfig options (outside the standard CONFIG_NET_BUF_* group) to allocate more buffers or memory specifically for the Net Core's PPP function in NCS v2.5.0?[/quote]

Regarding buffers, please refer to network buffer configuration options.

[quote user=""]PPP RX Stack: Is CONFIG_NET_PPP_RX_STACK_SIZE=8192 an adequate stack size for high-traffic scenarios on the nRF5340, or should this be increased further?[/quote]

It is generally advisable to check if stack sizes are appropriate using thread analyzer.

Best regards,
Dejan
