Bluetooth module build

Ok so i live in mexico and want to make my own Bluetooth modules 1- do I need to program the hm-10 or not? 2- are this the connectors ? image

Help @rey8801 hehe

You need JST PH 7 pins. Well you will use 4 pins in total so they will also work but why bother about it when you can get it for cheap anyway. I will post one link. For the module depends which phone you have and which module you buy. Which phone do you have?

I have iPhone 7 but I would like to make for iPhone and Android

for iphone you don’t need. For Android Oreo there is the risk. Is not that diffiucult. I found that this clone in 80% of the case works with Android too But better to flash it because can be that with futher updates it won’t be compatible anymore. That what I do for the modules I see


Do i have to program it ? And do you have a correct wire diragram

If you read above I just answered. I have like 20 of them. The most recent ones work with Android Oreo. Although I can not be sure it will work in the future. In case you can flash it later

Here we go Check on YouTube like flash hm10 firmware on… And you will find a video too.


Just want to say that after flashing mine with the original HM-10 firmware, it works a lot more reliable with my iPhone on iOS 11. It used to fail to write configs using Xmatic app and took several tries to make it work.
