How to use OTA to update the coordinator program

Hi:

We currently use JN5189 to develop a gateway, and JN5189 uses UART1 to communicate with the WIFI chip. We want to upgrade the program of the coordinator via WIFI. What should we do? Is there any routine for reference?

Hi,

I hope you are doing great.

Just to confirm, do you want to update the MCU throught UART interface, am I wrong?

However, you could look at the app_ota_client.c file

#if (defined OTA_INTERNAL_STORAGE)

You could look at the comments about the flash and the sectors that are used. Unfortunately, we do not provide a bootloader that helps you to implement the update using serial communication.

Look at the JN-AN-1244 to take as reference the OTA update.

Regards,

Mario

Hi,mario:

Yes, we hope to receive the upgrade package sent from the WiFi chip through USART1 and update the coordinator program.Ok, I see, thanks for your reply.
