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)
Hello all

hi i have linux server connected to internet through a switch/router. i have opened a port on the router and i am able to connect to the server if iptables is off. but when it is on i cant.

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.

Normally I have very good experiences buying from AliExpress, but in this case with Elecrow, I'm disappointed.
After confirming with Elecrow on AliExpress that their Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield for Arduino would work with 3G SIM cards in Thailand, I purchased one. My plan was to... (1 Reply)
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:

gpioctl
GPIOCTL(8) BSD System Manager's Manual GPIOCTL(8)NAME
gpioctl -- control GPIO devices
SYNOPSIS
gpioctl [-q] device attach device offset mask [flag]
gpioctl [-q] device pin [0 | 1 | 2]
gpioctl [-q] device pin [on | off | toggle]
gpioctl [-q] device pin set [flags] [name]
gpioctl [-q] device pin unset
DESCRIPTION
The gpioctl program allows manipulation of GPIO (General Purpose Input/Output) device pins. Such devices can be either part of the chipset
or embedded CPU, or a separate chip. The usual way of using GPIO is to connect some simple devices such as LEDs and 1-wire thermal sensors
to its pins.
Each GPIO device has an associated device file in the /dev directory. device can be specified with or without the /dev prefix. For example,
/dev/gpio0 or gpio0.
GPIO pins can be either ``read'' or ``written'' with the values of logical 0 or 1. If only a pin number is specified on the command line,
the pin state will be read from the GPIO controller and displayed. To write to a pin, a value must be specified after the pin number. Val-
ues can be either 0 or 1. A value of 2 ``toggles'' the pin, i.e. changes its state to the opposite. Instead of the numerical values, the
word on, off, or toggle can be used.
To
Only pins that have been configured at securelevel 0, typically during system startup, are accessible once the securelevel has been raised.
Pins can be given symbolic names for easier use. Besides using individual pins, device drivers that use GPIO pins can be attached to a
gpio(4) device using the gpioctl command. Such drivers can be detached at runtime using the drvctl(8) command.
The following configuration flags are supported by the GPIO framework:
in input direction
out output direction
inout bi-directional
od open-drain output
pp push-pull output
tri tri-state (output disabled)
pu internal pull-up enabled
pd internal pull-down enabled
iin invert input
iout invert output
pulsate
pulsate output at a hardware-defined frequency and duty cycle
Note that not all the flags may be supported by the particular GPIO controller.
When executed with only the gpio(4) device name as argument, gpioctl reads information about the GPIO device and displays it. At securelevel
0 the number of physically available pins is displayed, at higher securelevels the number of configured (set) pins is displayed.
The options are as follows:
-q Operate quietly i.e. nothing is printed to stdout.
FILES
/dev/gpiou GPIO device unit u file.
EXAMPLES
Configure pin 20 to have push-pull output:
# gpioctl gpio0 20 set out pp
Write logical 1 to pin 20:
# gpioctl gpio0 20 1
Attach a onewire(4) bus on a gpioow(4) device on pin 4:
# gpioctl gpio0 attach gpioow 4 0x01
Detach the gpioow0 device:
# drvctl -d gpioow0
Configure pin 5 as output and name it error_led:
# gpioctl gpio0 5 set out error_led
Toggle the error_led:
# gpioctl gpio0 error_led 2

The gpioctl command first appeared in OpenBSD 3.6 and NetBSD 4.0.
