I have a question concerning the datarate of the usart1 interface of the SL8092 module.
The datasheet says (section 4.5) that the module supports speeds up to 4 Mbps.
If I ask the module with AT+IPR=?, it answers with
It seems that it supports a maximum baudrate of only 230400 bps.
How can I get the promised 4 Mbps?
Thanks in advance,
