@ GHI any news… I need to take serious decision on how to continue if this issue can’t be solved within a reasonable period of time. It’s hard me for me to imagine that the problem is not seen at GHI because i am not the only user mentioning this problem.
IIRC, you said this problem didn’t happen a second time so it must be extremely rare to happen.
#7 was the second time… i was waiting and i didn’t report more events after you wrote
"we might have something" 2 other customers returned their device this week with corrupted flash. if the config flash is corrupted it start to output low level exceptions at the serial port
@ Gus - We’ve saw the problem with the G120 modules, the reason we wouldn’t see it more is because we had to shelve the G120 design and go back to the EMX until firmware problems with the G120 were fixed.
Dat reported he had fixed the problem with USB disconnection not being reported, and it would be out in the next SDK release. You also said hibernate support was close, and we were hoping to see that soon too. Do you have any time-frame for an SDK with those fixes?
SDK comes very soon. No set date yet but we are working on it very closely.
Please email to GHI and we will send you a fixed firmware for testing!
@ Dat - Unfortunately this fix did not solve the issue that config flash gets corrupt and exceptions messages are send to com port 
I used the following setup:
A custom G120 board connected to a power supply that switch on automatically and leaves power at the board for 1,5 minute. after 1.5 minute it switches the power down for 2 seconds and starts over.
The test code is basicly setup the RS9110 module. The first time as infra structure mode and the next time the system startsup it will setup RS9110 in AD-Hoc mode.
Changing the wifi mode makes sure that write actions take place to flash.
After 132 startups the system crashed.
@ RobvanSchelven -
Show us that code, please!
@ Dat - I did a second test… after 150 cycles it crashed again. I changed the code to start-over faster, instead of waiting 1,5 minutes… i just wait 2 seconds once Wi-Fi was initialized and running. this 3th test after about 30 cycles the system starts to output the following message to com1
6:21:13.985 socket available=0
6:21:14.254 socket available=0
6:21:14.523 socket available=0
6:21:14.791 socket available=0
6:21:15.60 socket available=0
6:21:15.328 socket available=0
6:21:15.596 socket available=0
6:21:15.865 socket available=0
6:21:16.134 socket available=0
6:21:16.402 socket available=0
6:21:16.670 socket available=0
I know you need code to test but this will cost me again a large amount of time to isolate it. I am not sure if i need to invest more time in to this module
@ RobvanSchelven -
Just one thing I can say is, let me try to reproduce it on Monday.
One more question:
Does “6:21:13.985 socket available==0” come from your Debug.print() or you just see it over com port?
One customer confirmed bug overload number socket is gone (he didn’t see it in one week and continue testing) , it can be destroyed by self, doesn’t matter global or local, so it is weird for me.
@ Dat - Below you find code to reproduce the low level exception. The socket available=0 comes from my debug print. I think we can forget it for a while because i need to do more testing on that.
You need to run the code for a while. Here the exception shows up after about 130 itterations

@ Dat - I’ve just done some testing with the 9.2.10.2 firmware you sent, and the failure to see USB disconnection problem is still there.

So it seems that USB disconnected detection is not reliable or usable yet.
@ Dat - I’ve done some more testing with the G120 9.2.10.2 test firmware, this time testing the hibernate function.
Hibernate now appears to work, rather than crashing immediately as with the previous version firmware. Awakening after a short period of hibernation works correctly, however after hibernating for a longer period the device crashes immediately after awakening.
I can’t quantity the periods as yet - I’ll try adding a time-stamp to the debug prints and do some more testing when I get a chance. However identical code running on the EMX functions robustly.
Debug output from hibernate sequence. First was short, only a few seconds. Second, where it crashed, was a few minutes. It just kept on with the “Exception 6” messages until reset.

@ C-Born -
Hi, thank for your feed back
I just ran code from that link and the result is good. Are you using same that code or different one? if so, can you show us please?
And is it 100% you can reproduce it?
And, one time it happened, how about if you unplug and reconnect again? Does it still work incorrectly or correctly after that?

@ ianlee74 - I think DAT needs a holiday break 
It’s looks like morning fingers before coffee has time to work syndrome!! 
It is a big Whale like creature I think
