MLT-BT05 BLE module – a clone of a clone?? 148

MLT-BT05 BLE module - a clone of a clone??
Previously I covered the HM-10 Bluetooth Low Energy (BLE) module and its clone, the CC41-A.  Those are two popular modules that allow simple BLE communication through a serial interface and are handy with Arduinos and other hobby micro controllers. Make sure you read that article first as it provides important background for this curious update. ...

HM-10 or CC41-A module? Automatic Arduino BLE module identification
Lately I am working a lot with Arduino, which is a new field for me, hence fewer posts. Arduino is a very popular entry level embedded electronics platform. My latest Arduino project features Bluetooth Low Energy (BLE) communication. Arduino boards have no built-in BLE capabilities so I was looking to add a BLE module to ...

Arduino sound level meter and spectrum analyzer
Recently I have been doing some projects with the Arduino electronics platform. One of the projects involved benchmarking certain motors and required me to measure noise levels. I  will cover that project in more detail in one of the future articles, but now I would like to write about the process and best practices of ...
