Dear Engineer, 

For the application layer, is it possible to get the Aps ack? Since I need to know if the device has received message or not. 

Is there any function callback I can use?

Thanks! 

this happened very rare, but once it happened, we need the solution,  is there any comand  or API to trig "EMBER_NETWORK_UP"?

if I can't recover the previous network, all the devices need to left and rejoin the gateway, it take a lot of time...

because the Z3GatewayHost is running background, I can't use CLI, below is the log.

Dear Engineer,

I'm running Z3GatewayHost for over a month without problem, but today I found a problem, the gateway can't send messages to the routers and end devices.

I checked inside, and found "EMBER_NETWORK_DOWN", I don't know how it caused "EMBER_NETWORK_DOWN" for the gateway, is the NCP working too long time?

This is a very serious problem, if the gateway network is down, all the devices can't be control....

please help

Dear YK,

I use a button to trig the device to send the message, before it powered off, it can send to gateway normally, but after power cycle, when I pressed the button, it show the tx error, the message can't reach the destination.

I'll try new version, thank.

But if the device uses version 6.9.2.0, the gateway side can sitll use 6.7.6? or the gateway side MUST use the same version?

sorry for the late reply, I'm using the EmberZnet 6.7.6.0
