• @Wilberforce I have added the antenna - getting the same result. esp-open-rtos works fine with and without the antenna though.

    @CrashingDutchman It's being powered through USB out of my laptop - same power source as with esp-open-rtos. Just tried powering it with 12V 1A adapter - didn't see any improvement. Also erased and re-flashed using the new power source.

    What else can we try? :D
