868Mhz, 4GFSK, 433.333ksps, Crystal 26MHz, project used is Standard packet Tx and RX;
The result:
the time used for Tx State is 357us.
Desired aim:
2400~4800 transmissions in 1 second,6 bytes per transfer.Transmission distance is 0.5 meter.very low bit error rate.
Question:
How to configure to reduce the transmission time? Frequency,Modulation,Data rate,Packet handler(preamble,sync word),example project(standard packet transmission,long packet transmission)

Hi Yazhou,
The Standard packet TX and Standard packet RX applications doesn't support packet configuration on the GUI (this is where their names come from), though you can modify the generated radio config array by hand. However, for custom packet configuration use the Custom packet TX and RX examples, where you can customize the Preamble, sync word, payload fields as well as the CRC configuration.
On sync word selection see this article, and consult with the device's datasheet for the recommended preamble length configuration.
