PSoC 4 MCU

New Contributor

Hi,

I am working on setting up radio tests for a product with PSOC 4 BLE using MTK BLE interface. I used the TXP as well as TXC cmd to setup transmit tests, but the duty cycle as observed on the RF spectrum analyzer is ~60%. Is there any method I can increase it to >90%?

Thanks,

Jimit

Hi,

Setting the packet length to the maximum (255 bytes, using SPL command. E.g. SPL 255) will provide a duty cycle of 84.8%.

Setting the packet length to 193 bytes will provide the maximum duty cycle (86.6%)

The packets are sent as per timing specified by specified by the Bluetooth spec for packet interval, which is a function of packet length and the baud rate. So 86.6% is the maximum achievable.

Thanks
