Enabling second antenna, unstable Vocore 2

Fri Feb 02, 2018 6:21 pm


I wanted to check out the 300mB/s mode and enabled the second antenna according to the instructions.
It seems like the Vocore becomes unstable, I'm basically experiencing the same stuff like described in this post: http://forum.vocore.io/viewtopic.php?f=16&t=3529 - I guess it will just reboot around the point where the wifi driver is started.
This was deemed a power issue, but I've tried a variety of power sources (up to 2.5A) and cables without any luck.
I don't know what's a good antenna to use, I tried with this one: https://www.adafruit.com/product/2308
I noticed that if I disconnect the antenna, it's not as unstable and may complete the boot sequence and start the wifi (and I was able to confirm it's in 300mB/s mode), but it will still randomly cut off and reboot.

Best regards

this is a weird issue. antenna will not effect vocore or anything.
maybe it crosstalk to the chip and interference some kernel module?

if you have to use two antennas, better to remove the on board blue antenna, and use two u.fl connect to your antennas
