Do we have a return time contract in a BLE GAP event?

In my logic, I am performing work in a BLE GAP event handler. Specifically, I am looking at the responses that come back from a scan requests when my ESP32 is being a BLE Central. I see the events arrive and I do some processing on them. When I perform the scan, I specify how many seconds we should ...

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: Leshan

I'd never heard of "Leshan". I think this is what you are talking about:

Re: BLE event indicating client has changed characteristic value

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