Jacob commented on MYNEWT-755:
------------------------------

Heh. duh. Yeah I actually know that. I was probably using serial transport and 
then switched to ble not thinking.

EXCEPT, it turns out ble does work on ios when I use the GODEBUG=cgocheck=0 
flag :)

> Googling seems to indicate maybe it needs refactoring?
> https://github.com/ry/v8worker/issues/31
> Ive tried back to mynewt_1_0_0_b2_tag and it still happens so I think its 
> tied to again either xcode update or maybe a go point release?
> Jacobs-MacBook-Air:newtmgr jacobrosenthal$ go version
> go version go1.7.5 darwin/amd64
> My xcode is 8.3.2
> But I can confirm the listed workaround is to use GODEBUG=cgocheck=0 works 
> but I get (possibly unrelated?) unhandled xpc events as well
