sniffer works fine no mattter what baudrate I set

[ruiqi]

When I use nRF52840 dongle as a promiscuous packet sniffer, I found that sniffer works fine no matter how much I set the baud rate. This happens only on the dongle, so I want to know if there is a mechanism for adaptive baud rate on the dongle?

Hi,

If you are using the nRF52840 dongle, then this does not use UART, as awneil wrote. You are also mentioning a TI product (CC2538), so I am not sure what you are doing. Please contact TI for any questions regarding their products.
