It is definitely waking up, when the message isn’t posted i can see in the broker logs that it did connect but was disconnected due to timeout. Would it be 100% “awake” at this point and that’s no longer on the list of possible issues? The wifi is 100% fine i’m sure, i’ve got them testing just now with an rssi of -40 +/- 5 (I dont think i can practically improve on that) mainly looking into whether the voltage pull on wake up is occasionally tripping it up, have new caps coming tomorrow to try a different build as shown in previous post, just wanted to check i was planning to put them in the right places.
