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:

With a little bit of work, was able to build a nice "Wuhan Coronavirus Status" app using MQTT and the IoT-OnOff app. More on this technique here:

gpioiic
GPIOIIC(4) BSD Kernel Interfaces Manual GPIOIIC(4)NAME
gpioiic -- GPIO I2C bit-banging device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device gpio
device gpioiic
device iic
device iicbb
device iicbus
DESCRIPTION
The gpioiic driver provides an IIC bit-banging interface using two GPIO pins for the SCL and SDA on the gpiobus. gpioiic implements an open
collector kind of output, as recommended by the standard, when driving the pins on the gpiobus, i.e, they are never switched to the logical
value of '1', or they are '0' or simply open (Hi-Z/tri-state). So the pullup resistors are required so gpioiic can work.
On a device.hints(5) based system, like MIPS, these values are configurable for the gpioiic:
hint.gpioiic.%d.at The gpiobus you are attaching to. Normally just gpiobus0.
hint.gpioiic.%d.pins This is a bitmask of the pins on the gpiobus that are to be used for SCLOCK and SDATA from the GPIO IIC bit-banging
bus. To configure pin 0 and 7, use the bitmask of 0b10000001 and convert it to a hexadecimal value of 0x0081. Please
note that this mask should only ever have two bits set (any other bits - i.e., pins - will be ignored).
hint.gpioiic.%d.scl Indicates which bit in the hint.gpioiic.%d.pins should be used as the SCLOCK source. Optional, defaults to 0.
hint.gpioiic.%d.sda Indicates which bit in the hint.gpioiic.%d.pins should be used as the SDATA source. Optional, defaults to 1.
On a FDT(4) based system, like ARM, the DTS part for a gpioiic device usually looks like:
gpio: gpio {
gpio-controller;
...
gpioiic0 {
compatible = "gpioiic";
/*
* Attach to GPIO pins 21 and 22. Set them
* initially as inputs.
*/
gpios = <&gpio 21 1 0
&gpio 22 1 0>;
scl = <0>; /* GPIO pin 21 - optional */
sda = <1>; /* GPIO pin 22 - optional */
/* This is an example of a gpioiic child. */
gpioiic-child0 {
compatible = "lm75";
i2c-address = <0x4f>;
};
};
};
Where:
compatible Should always be set to "gpioiic".
gpios The gpios property indicates which GPIO pins should be used for SCLOCK and SDATA on the GPIO IIC bit-banging bus. For more
details about the gpios property, please consult /usr/src/sys/boot/fdt/dts/bindings-gpio.txt.
scl The scl option indicates which bit in the gpios should be used as the SCLOCK source. Optional, defaults to 0.
sda The sda option indicates which bit in the gpios should be used as the SDATA source. Optional, defaults to 1.
