Re: Problems with kolban's cpp_utils WiFi.h

Howdy ... in your code you coded: WiFi *pWifi = new WiFi(); and later on coded: pWiFi->connectAP("SSID", "PASSWORD"); In the first fragment, the name of the variable was "pWifi" while in the second it was "pWiFi". Note the change in case between the variable n...

[Answered]: Building apps for OTA distribution ...

I've been reading about OTA. Imagine I have two partitions for OTA program storage. Lets call them ota_1 and ota_2. I also believe I need the "factory" application. Imagine I distribute an ESP32 pre-loaded with my end-user application. My understanding is that it will be hosted in the &quo...

Re: Simple example for transmit data from ESP32 bluetooth to mobile

You might get some mileage out of Blynk (http://www.blynk.cc/). It is higher level than API programming but now claims Bluetooth support in addition to WiFi.

Re: how to connect two esp32 boards

Howdy @DowJohn,
BLE is a bluetooth protocol used to transmit relatively short packets of information. An ESP32 can be either a BLE client, a BLE server or both. If you have two ESP32s, one can be a BLE Server, one a Client and they can exchange data between each other.

Re: How can scan particular BLE devices?

Can you elaborate on "pBeacon"? Do you have any links or references to further explain what you mean? Typically, a BLE device advertises using BLE advertising packets. The content of the packet is under the governance of the BLE server that is transmitting. The content of the packet must a...

Re: BLE_SCAN_TYPE

Howdy ... unfortunately I think that's a tall order. What I'd like to suggest is to get some books on BLE. I bought a subscription to Safari on-line books and have read three now and its just starting to make sense. The specifications for BLE and public at the BLE web site but a little "dry&quo...

Re: uart_read_bytes

In your original post you asked if we waited or returned immediately when the "length" bytes were available. I think you shouldn't discount a third option which I believe may also exist ... that it returns immediately if LESS than "length" bytes are available but at least 1 byte....

Re: ESP32 softap program in Arduino

I haven't heard of any issues in this area. Can you elaborate on the concept of none of your GPIOs are responding to input. Are you saying that when you read a value, the value read doesn't match your expectation or are you saying you have registered interrupt triggers and the interrupts don't appea...

Re: The BLE APIs and the concept of "handles" ...

In my travels, I wanted to create a C++ framework for working with BLE and created the library that can be found here: https://github.com/nkolban/esp32-snippets/tree/master/cpp_utils My goal is not to have you use that library but instead maybe skim it for API usage. I made extensive use of handles ...
