Part Number: CC2544
I use CC2544 as the 2.4G USB dongle for the Bluetooth keyboard, but the transmission distance is only about 3m in the actual scene. What parameters should I debug to increase the transmission distance and sensitivity? This is my schematic.
I am not certain what you mean with using CC2544 towards a Bluetooth keyboard. The CC2544 does not have any BLE-Stack software offering. What software is running on the CC2544?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I use CC2544 on the USB dongle of 2.4G RF. The Bluetooth chip that matches it is on the Bluetooth keyboard. But the 2.4G transmission distance is only 2-3 meters. I tried to modify the capacitance of the peripheral circuit, hoping to increase the transmit power, but it does not increase the transmission distance.
In reply to Peggie:
I do not understand what you mean from a software POV. Anyhow, i'm assigning this thread to the HW team as this seems related to the HW design. Please share the PCB layout if possible,
Can you try to follow the steps described in this application report? http://www.ti.com/lit/pdf/swra603
