AltSoftSerial uses these pins on the Arduino UNO, according to AltSoftSerial_Boards.h (included with the AIS NB-IoT libs):
My BLE module sketch (taken from an ArduinoBlue example sketch) uses pins:
So, not yet more more than an Arduino noob, my first guess is that I should move the Arduino UNO pins for the HM-10 BLE module to some supported SoftwareSerial pins which are different than the AltSoftSerial pins (8,9) above.
Seems the conflict is pin 8 being used by both SoftwareSerial (used in the BLE code) and AltSoftSerial (used in the NB-IoT code).
Will try different pins tomorrow and see how far that get me.
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.

linkcomp
LinkComp(3U) InterViews Reference Manual LinkComp(3U)NAME
LinkComp, LinkView, PSLink - component subject, view, and PostScript external representation for lines with connectable endpoints
SYNOPSIS
#include <Unidraw/Components/link.h>
DESCRIPTION
LinkComp is a GraphicComp defining a line with two pins on each end. The line's endpoints will always coincide with the pins, even if they
are moved, thereby maintaining a graphical link between the objects to which it is connected. LinkComp uses an Line graphic to define its
initial geometry and graphical attributes. LinkView is a GraphicView for displaying the link. PSLink is a PostScriptView that external-
izes the subject's information in PostScript form.
LINKCOMP PUBLIC OPERATIONS
LinkComp(Line* = nil)
The constructor takes an optional line graphic to define its initial appearance.
virtual void Interpret(Command*)
virtual void Uninterpret(Command*)
In addition to (un)interpreting the commands GraphicComp (un)interprets, LinkComp also (un)interprets DeleteCmd and CutCmd by pass-
ing these commands to its pins for (un)interpretation.
virtual void Update()
When the LinkComp's pins move to maintain connectivity, LinkComp will reorient the line so that its endpoints and the pins coincide.
virtual void First(Iterator&)
virtual void Last(Iterator&)
virtual void Next(Iterator&)
virtual void Prev(Iterator&)
virtual boolean Done(Iterator)
GraphicComp* GetComp(Iterator)
void SetComp(GraphicComp*, Iterator&)
LinkComp redefines GraphicComp's traversal operations to make its pins accessible to the Unidraw library. Thus Unidraw can deter-
mine the connectors that belong to the component and call its Update operation only once for efficiency. The traversal does not
include the line.
Line* GetLine()
Return the Line graphic that defines the link's attributes. GetLine is simply a more specific form of the GetGraphic operation.
void GetConnectors(Connector*&, Connector*&)
Return the LinkView's pins, which are stored in the _conn1 and _conn2 protected members.
LINKVIEW PUBLIC OPERATIONS
LinkView(LinkComp* = nil)
Create an LinkView, optionally supplying the subject.
virtual Manipulator* CreateManipulator(
Viewer*, Event&, Transformer*, Tool*
)
virtual void InterpretManipulator(Manipulator*)
LinkView redefines its response to manipulation with a GraphicCompTool. The user clicks to specify the first endpoint of the link
and then drags to position the remaining endpoint. (Up)clicking on an existing connector will establish a connection between it and
the LinkComp's first (second) pin. LinkView uses a ConnectManip to produce a gravitational attraction between existing connectors
and the second pin as the user drags to position it. The endpoints will not be constrained by gravity. LinkView will use Con-
nectCmds to connect the pin(s) to their target(s). Pin(s) connected in this way will receive floating mobility; unconnected pin(s)
will be fixed.
virtual void First(Iterator&)
virtual void Last(Iterator&)
virtual void Next(Iterator&)
virtual void Prev(Iterator&)
virtual boolean Done(Iterator)
GraphicView* GetView(Iterator)
void SetView(GraphicView*, Iterator&)
LinkView redefines GraphicView's traversal operations to make its pins accessible to the Unidraw library. Thus Unidraw can deter-
mine the connectors that belong to the component, for example, to support ConnectManip's gravitational attraction effect.
virtual void GetEndpoints(Coord&, Coord&, Coord&, Coord&)
Return the link's endpoints, in canvas coordinates.
LinkComp* GetLinkComp()
Return the subject.
LINKVIEW PROTECTED OPERATIONS
virtual void CreateHandles()
LinkView redefines CreateHandles to use a RubberHandles object with two handles, one at each endpoint of the link.
Line* GetLine()
Return the line that LinkView draws between its pins.
virtual LinkComp* NewSubject(Line*)
A helper function that creates a LinkComp subject with the given line graphic. This function produces the proper subject when the
GraphicCompTool's manipulator is interpreted. Subclasses can redefine this operation to return a LinkComp subclass, thus eliminat-
ing the need to reimplement InterpretManipulator.
Manipulator* CreateLinkCompManip(
Viewer*, Event&, Transformer*, Tool*
)
Command* InterpretLinkCompManip(Manipulator*)
Helper functions that CreateManipulator and InterpretManipulator use to create and interpret the manipulator for GraphicCompTool.
PSLINK PUBLIC OPERATIONS
PSLink(LinkComp* = nil)
Construct a PostScript external representation of the given subject, if any.
