### 3/5 — Idk

Cannot get the blaster to marry. It will connect to wifi but will not marry.

### 1/5 — Jk blaster will not pair

*2023-09-27*

The jk blaster will not pair with my I phone 

I’m using the 12345678 code/password

### 5/5 — The app does not work

*2021-06-08*

Blaster app has no place to allow location services which in turn does not allow sync between the app and device. I need help.

I received a prompt response from the developer regarding the issue. They are hoping to have a patch issued. Hopefully it solves the issue.

Matt was able to fix the issue and I am now good to go. Thanks so much for the effort.

**Developer response:** Hello,

Historically Core Location has never been a requirement to allow apps access to wifi information, however a more recent iOS update has killed this prospective. I’d estimate in the past 3 weeks. I went ahead and started to patch this bug. I should have a fix out for it soon, if you have access to Android you can use the stable release there. As always, you can contact me at support@zautotech.com and ask for Matt. 

Update: I fixed the application and I’m pushing the update to apples review team, please be patient sir.
