For an important project, I buy 30 ConnectCore Wi9P9215 modules. The 30 modules have the same software. Then, we test these 30 modules separately.
After 10 minutes, I have 9 modules that the network disappear. It is very strange because all 4 serial liaisons are ok, all gpios are ok, the processor is ok. But there is a problem with the wifi, it doesn’t respond to ping commands after 10 minutes.
There are no problems with other 21 modules, after 1 week to run, each module and wifi are always ok.
Have you got an idea for this problem ? Have you already seen that ?
I would try factory defaulting the 9 units and see if that helps. If that doesn’t help try changing the antennas with the ones that work.
Does rebooting the failed modules solve the problem? I mean, do you have connection back immediately after rebooting and you loose it again after ten minutes?
If I reboot the failed modules, it doesn’t solve the problem. I have connection back immediately and I loose it again after 10 minutes.
I try to change the antennas but it doesn’t solve the problem.
In your case, I would contact their technical service:
I have contacted their technical service but no response
Which OS variant are you using?
try running the same tests on the development board with a default NET+OS image. Does that help?
I try the same tests on the development board with a default NET+OS image. I have changed parameters in order to be in a join or create, adhoc mode.
But the problem isn’t solved. Wifi is lost after 10 mn with failed modules.
