The "conflict" was solved by moving the BLE pins from my original ArdunioBlue example sketch from (8,7) to (7,6):
Code:
// The bluetooth tx and rx pins must be supported by software serial.
// Visit https://www.arduino.cc/en/Reference/SoftwareSerial for unsupported pins.
// Bluetooth TX -> Arduino D7 was D8
const int BLUETOOTH_TX = 7;
// Bluetooth RX -> Arduino D6 was D7
const int BLUETOOTH_RX = 6;
SoftwareSerial bluetooth(BLUETOOTH_TX, BLUETOOTH_RX);
So, I've confirmed the NB-IoT shield is sending / receiving data and the BLE app is sending and receiving data:
Code:
23:18:37.770 -> ################################################################
23:18:37.841 -> # Sending Data IP=209.126.XXX.XXX PORT=YYYYY
23:18:37.917 -> # Data=50696e6720436f756e743a203133
23:18:37.917 -> # Send OK
23:18:37.917 ->

23:18:38.215 -> # Data=424c4520427574746f6e2031
23:18:38.253 -> # Send OK
23:18:40.076 -> Button: 5 <------ ArduinoBlue test data from iPhone
23:18:43.679 -> Button: 0 <------ ArduinoBlue test data from iPhone
23:18:48.946 -> Button: 99 <------ ArduinoBlue test data from iPhone
Tomorrow, if all goes according to plan and I get time to work on this, will do the next step in merging these two apps together and see if I can push a button on the iPhone and get the result on the remote Linux server (I'm confident this will be easy now); and then I'll write some mini-apps, like pressing a button on the iPhone and requesting the load averages of the server and pressing another button and getting some other metric like total number of users on the server.
From here, the rest of the coding should be a piece of cake.
More tomorrow.....
PS: One thing I am starting to notice is the lack of programming space (flash memory) on the UNO:
Code:
Sketch uses 20012 bytes (62%) of program storage space. Maximum is 32256 bytes.
Global variables use 1055 bytes (51%) of dynamic memory, leaving 993 bytes for local variables. Maximum is 2048 bytes.
Looks like I'll be moving to the Raspberry PI sooner than later
I just moved away from a T3 line back to a dial up I just wanted to know would a P200 with 64meg and a 4 gig hard drive be ok for a linux server for an additional 3 pcs all running win98. I will be dialing into an isp using a 56k v90 modem.
Any support or help will be great. (3 Replies)

My favorite projects are always related to the "latest" tech in command and control, networking and network communications. This Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield seems to be the "latest and the greatest" as far as 3G and GPS, as far as I can see so far, but I has it drawbacks for sure.... (6 Replies)
Today I received my NB-IoT Arduino Shield for AIS (Thailand). Here is a "pinout" photo of the shield.
My shield looks just like the one above, for the most part. I'll post another photo of the actual device later.

Here is a sketch to do basic testing for the Arduino UNO and the MLT-BT04.
This BLE module works with IOS (iPhone) and I'll add some details on my IOS testing with an iPhone in a follow-up post.
For now, here is the basic BLE (HM-10) sketch for the Arduino UNO:
