What is the baud rate of JN5169 once it will enter in program mode, can anyone answer.
A reference would be better if you have any.

I have read JN-AN-1003.pdf But in that, they have not specified for JN5169.

And also, Can anyone elaborate what is 8, N, 1 in the attachment.

Hi, Sebastian Thanks for your kind replay.

I'm doing program JN5169 through FW.
Note - Host-JN5169 is working at 115200 baud rate 

Following are the steps to update JN5169 from Host(using  firmware)
1)The host is changing current(115200) baud-rate to 38400.
2)Sent "Change Baud Rate Request" to JN5169.
3)Wait for the "Change Baud Rate Response" from JN5169.
4)Once "Change Baud Rate Response" from JN5169 Host is change baud-rate to 115200 from 38400.
5)Start further process(Read module details and extract FW information from FW and start flashing FW in JN5169)

Feel free to ask more information.

Thanks and regards,
Hiren Virapara :smileyhappy:

Hi Hiren,

 

Could you please take a look at JN-AN-1110? It can be found in this page of our website, and it provides code and guides relating to a programmer application that is already implemented and could help you create your own programmer.

 

It's important to note, however, that since we already provide a programming application for JN516x devices (implemented in BeyondStudio IDE), this implementation is custom and not supported.

 

If you need any more information, please let me know.

 

Best regards,

Sebastian

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
