Re: ESP32 web server with AJAX functionality

My perspective on SNMP vs REST is that they serve dramatically different purposes. REST is a client/server based protocol used to send update requests to a partner or request data from the partner. SNMP is all about efficiently retrieving/querying status information about a device. While if what you...

Re: BLE event indicating client has changed characteristic value

Almost by definition, a BLE Server (the ESP32 in your story) is a custom piece of software. As best I understand, there is no industry API that has been standardized so how one writes BLE Server code is a function of which library you are using. At the BLE lowest level, the BLE client sends a radio ...

Re: BLE event indicating client has changed characteristic value

Imagine you have two BLE devices ... lets call them A and B. Let us now assume that device A is being a BLE server and device B would then be a BLE client. Device A (the server) ... starts up and starts advertising. It now passively sits there waiting for a client to explicitly connect with it. Devi...

Re: How to interface LSM6DS3 with ESP32

In principle, many of the Arduino libraries will compile and run cleanly on an ESP32 Arduino platform. Have you had a go trying to compile the Arduino libraries in an Arduino ESP32 environment? If yes, what issues were encountered?

Re: BLE event indicating client has changed characteristic value

In your story, is the ESP32 the BLE Client or the BLE Server?

Re: How to compile single component

It should be that the source of a component is only compiled/recompiled when the source of it changes. Are you asking about creating "libraries" of pre-built components as opposed to the idea of compiling a single component? The down-side of building a pre-made library is that the componen...
