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 ?
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. https://www.aliexpress.com/item/10-Sets-JST-2-0mm-PH-7-Pin-Female-Housing-Connector-with-Wire-and-Male-Connector/32823550472.html?spm=a2g0s.90423220.127.116.11424c4dPX360m 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 https://www.aliexpress.com/item/AT-09-BLE-Bluetooth-4-0-Uart-Transceiver-Module-CC2541-Central-Switching-compatible-HM-10/32460561807.html?spm=a2g0s.9042318.104.22.168424c4dZKdfqb. 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
The wire diagram is posted everywhere on the forum
HM-10 / vesc VCC / 5V GND / GND RX / TX TX / RX
Ok i así about this because the ones that I bought where connected to 3v
this module handles 5V no problem
Would u happen to have a link on how to flash the modules for oreo?
Here we go https://forum.arduino.cc/index.php?topic=393655.0 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.
