OTA Client doesn't answer to Image Notify.

I sporadically receive an AF_INCOMING_MSG with status C3 ( NWK_NOT_PERMITTED) for the image notify command.

Hi Ayman,

Please closely study the zc_ota_server and zr_sw_ota_client_offchip over-the-air communication with a sniffer when attempting to replicate results.  AF_DATA_CONFIRM proves that the message was sent over-the-air but likely does not have packet contents which agree with the receiving node device.  ZNwkNotPermitted indicates that the node has not joined the network and/or does not recognize the other node.  If the manufacturer flag is disabled then I do not understand the Manufacturer Code, and unicast messages are not directly related to default responses.

Manufacturer flag is disabled; the manufacturer code is intended as part of the image notify payload, which is mandatory if payload type is greater than 0x00.

For the default response, in the case of Image notify it depends upon the message receiver: set if multicast/broadcast otherwise is not set. You can see this below.

Regarding the network not permitted action i'm not fully convinced with the given answer. I will reset and recreate the network and rejoin the device.

Have you gotten the default Z-Stack OTA Upgrade demo to operate correctly, and what is the difference between setups and OTA messages?

I have OTA Server fully working but I can't sniff it.

Here is the OTA Server Sniffing:

Looking at Image Notify command the Payload type is 0x00 and Query Jitter = 100, same as me with the same Frame Control so I don't understand why doesn't work for me.

I'm running ZNP on my dongle. How do i check if OTA Server is enable on it?

This is my sniffing: Same network key

I'm glad to hear that you've resolved the problem.  Do you have any additional questions or concerns regarding the Zigbee OTA process at the moment?
