Hi Hiren, I hope you're doing well!
In programming mode, JN5169 devices can be programmed in a 1000000 Baudrate, which is the default option when opening the device programmer in BeyondStudio IDE.
The 8, N, 1 refer to the UART configuration used for programming:
- 8 refers to 8 data bits each packet.
- N refers to the fact that no parity is being used.
- 1 refers to the use of only one stop bit to end of the transmission.
For more information, could you please take a look at this document here?
Please let me know if you need any other information.
Best regards,
Sebastian
