I want to use nrf52833 as the keyboard and nrf52820 as the dongle.Refer to the example of
ncs1.3.2\nrf\applications\nrf_desktop, I want to add the LLPM of nrf52820.
But there is Only app_ZDebug.conf configuration of ncs1.3.2\nrf\applications
\nrf_desktop\configuration\nrf52820dongle_nrf52820 .
CONFIG_BT_LL_SW_SPLIT=y Use Zephyr SW LL, which seems to be due to insufficient RAM. How can
nrf52820dongle use Nordic SoftDevice LL?
What is puzzling is that I tried to use Zephyr SW LL without success.
Our company has nRF Desktop mouse and dongle hardware, when I configure it as follows (using
Nordic SoftDevice LL):
- west build -b nrf52840gmouse_nrf52840 -d nrf52840gmouse_nrf52840 -- - DCMAKE_BUILD_TYPE=ZDebug
- west build -b nrf52840dongle_nrf52840 -d nrf52840dongle_nrf52840 -- - DCMAKE_BUILD_TYPE=ZDebug
The mouse can be connected to the computer through the dongle.
However, when I try to use configuration (using Zephyr SW LL):
- west build -b nrf52840gmouse_nrf52840 -d nrf52840gmouse_nrf52840 -- - DCMAKE_BUILD_TYPE=ZDebugSplitLL
- west build -b nrf52840dongle_nrf52840 -d nrf52840dongle_nrf52840 -- - DCMAKE_BUILD_TYPE=ZDebugSplitLL
The mouse cannot be connected to the computer through the dongle.
