Application update with mesh sdk

finally, it's working.

firstly I send a status (DFU_PACKET_TYPE_STATE) message to the bootloader with the new version number and I download binary to the flash..

then I send a data (DFU_PACKET_TYPE_DATA) message with many informations for the DFU, This message payload data segment contains 0xffff, so the bootloader can separate this message from another data packet. Then the bootloader forwards this packet to a new function, which fills 'm_transaction' struct and starts the 'dfu_mesh_finalize()' function.

(I could have made a new type message (e.g. DFU_PACKET_DATA_DFU) instead of the data type, but I think this is no matter.)

simple, isn't it?

it's almost ready.

I added a new 'dfu_packet' message struct to the application and to the bootloader, which contains (I think) all necessary data for the update. After the bootloader received the data, it loads them to the 'm_transaction' static struct, then it calls the 'dfu_mesh_finalize()' function. The result is that the bootloader erases the application memory, writes the binary into the right place, more times changes the device page area, then restarts itself. After restart the application does not start correctly, but I can see, that the new application wanted to start.

not so easy....

Hi,

thank you that you deal whit this problem.

yes, the binary is in the flash of the target board, and I'd like to update only this device.

I tried to communicate with the mesh bootloader, which will validate the binary, but I think I have to send more info to it.

Hi.

So the new binary is already on the target board?
Is that the only device you want to update, or do you want to update other devices as well using Mesh DFU?

Hi,

unfortunately I could not find any solution yet. Maybe the concept is wrong? The main task is an application FW update via ethernet port.

any idea?
