• RedBearLab Arduino Blend V1.0 Connection Via Bluetooth to iPhone
• iiPhone 7 256GB Silver MNAU2LL/A
• Blynk Library version=0.5.4
• Trying to connect with these Blynk app settings:
- Connection Device: RebBearLab Blend Micro
- Connection Type: Bluetooth
The code below compiles with the following Arduino log:

When I press play button I get error that device is not connected. I am not sure how to get it connected or what I am doing wrong or if it is even possible with this old hardware.
In the Arduino console I simply endlessly get:
[504680] Connecting…
[513680] Connecting…
[522680] Connecting…
[531680] Connecting…
[540680] Connecting…
[549680] Connecting…
[558680] Connecting…
As a side note I use the code below to connect to the device via the IOs app LightBlue and send hex integers to trigger an Adafruit_NeoPixel. I am trying to use the Blynk app to do this more elegantly.

Adafruit_NeoPixel strip = Adafruit_NeoPixel(150, PIN, NEO_KHZ800 + NEO_RGBW);

//// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across

Any help would be greatly appreciated!!!
Sticking with WiFi and even USB serial for my stuff.
