I am trying to understand the operation of the serial bluetooth plugin in a simple application with Ionic 3 that communicates with an arduino nano connected to an HC-05.It seems that the plugin sends and receives the data in an ArrayBuffer, or array of bytes The information on the ionic page on this type of data is null, limiting itself to saying that it is an array of bytes .... after multiple tests and searches, trying to receive and send data, I only get strange characters whatever I do , so the question is, how exactly is this ArrayBuffer composed and how should I implement it in the arduino sketch to read and send data. Thanks.
