Hi,

We are using MCU to control this transceiver and using time syncronisation between nodes. We use 20Kbps data rate and expect for 5Byte preamble 2 byte sync word and 5 byte data to take 4.8ms. But, in practice we observe 9ms before a Tx complete interrupt. We have verified that this is not a MCU polling or other MCU latency. We have verified that SPI speed increase does not help. Can someone help us how we can improve the speed with the same data rate looking at the config file attached.
