I have three imps (well… more than that but these are important in this case).
Imp 1 connects to wlan. I can re-blink it up and it connects ok again.
Imp 2: I insert it to the same april-board and blink it up with the same phone and same settings: does not connect.
Imp 3: Same as Imp 2.
After blinking up Imp 2 or Imp 3, they try to connect to wlan:
They both do blink message led for “Searching WiFi network” once, “getting IP address” sequence for a while and then stop blinking.
If I insert Imp 1 to that same april-board, it connects ok.
I have tested this with three different April-boards. Same result: 1 works ok, 2&3 do not.
Just for fun I tested this with three different Wlan APs, with and without encryption. Same result.
Question: what could have killed my Imps (2&3) or are they dead at all and how do I get them working again?
Obviously they are not completely dead.
They used to work just fine some time ago. They have been just sitting in ESD-protected box since then and now when I tried to use them, they refuse to work.
MACs of Imp 2&3:
