Hello,
this is not really about Arduino and Wifi, but I don't know, where to better place the topic?
I want to build an application, which switches relais via Bluetooth.
I could use an HC-05 module and an Arduino Nano, while it is easy, the downside is more space required and higher current consumption.
So I read, that the HM-10 module can turn the GPIOs On and OFF via Bluetooth. However, it needs to get configured beforehand via serial interface. The question is, can the configuration get stored in the HM-10? Is it done automatically? Or via AT-command?
If the HM-10 does not save the configuration and restart the same way after a power cycle it is no good for my purposes.
Thanks for your help.
