Having some problems with the ArdunioBlue IOS app because I cannot find any method / sketch to send data from the Arduino BLE module to IOS. However, sending data to the Arduino BLE module from IOS works fine. Unless I am missing something huge, the ArduinoBlue IOS app is "one way communications" only, as far as the user is concerned. I sent an email to the developer, but it bounced as "undeliverable". I would prefer to have BLE comms bidirectional, obviously.
Edit(Update): I found more docs on ArdunioBlue and then found a method (which I have tested and it works) to send messages from the Arduino back to IOS:
Code:
void sendMessage(String text) - Sends the text to the phone as a popup

But after many tries, I cannot get the Blynk IOS app to connect to the Arduino BLE module, even thought it works fine with other IOS BLE apps, so I posted a question on this in the Blynk Community:
I am working on a semi-auto detection idea for Arduino for the Scope project.
It does require a little user intervention but minimal.
It works by just responding to two on screen prompts to unplug and plug Arduino
into a USB port.
There are two versions and both work perfectly well and give... (3 Replies)

Waiting for more fun Ardunio parts from AliExpress, I decided to test two cheap Chinese Arduino UNO clones.
The Arduino UNO R3 (CH340G) MEGA328P
The Wavgat UNO R3 (CH340G) MEGA328P
Both of these Chinese Ardunio clones sell for about $3 USD, delivered to your door.
