Hi jordanliu25,

So here are a couple of options for you. If you are going to upgrade multiple devices you should maybe consider using Mesh DFU. But you will need to update the first device through UART, then this device will store the update and then also forward it to the other devices withing radio range in the mesh network.

If you don't want to use Mesh or if we are only talking about a couple of devices to update you could also use a new feature which was introduce in SDK15.3 which lets you store a external application without activating it.

This way you could use you phone to update device A. Device A receives the update and stores it at bank 1 without updating its application. Then you will need to modify you application in device A to act as a DFU master to update device B. After device B is updated device A can activate the image and replace its own application. See the relase notes under "DFU" from SDK 15.3 for more information here.

Best Regards,

Marjeris

I would like to ask one host to upgrade multiple devices. Because our using environment request this function.

The host is standalone. It doesn't connect to a pc. Do you have any ideas how to make make the connection between host and receiver when upgrading the system? Receiver side may refer to the sdk examples.

Hi,

Could you explain you application a little bit more? Do you need to update only 2 devices or do you have have multiple devices to update? Can I ask why you want a device A to update device B? Why not use the phone (or the DFU master) to update both devices?

nRF Connect is also a good start for the host side.

Is the host connected to a pc or standalone? This will be important to know for the host side. FOr the side receiving the update in the sdk under DFU, those examples should give you the functionality your desire as is for the device being updated.
