Resize sdcard with parted

So I had to reinstall Debian in the sdcard of my Orange Pi Lite. Thing is original image / fs is only 4Gb, which on a 64Gb sdcard leaves 60Gb unused.

Here is where parted comes to the rescue. Easier than fdisk for me. Below example extends ext4 partition to 62Gb and creates a 2Gb swap partition.

sudo parted  /dev/mmcblk0 
GNU Parted 3.2 
Using /dev/mmcblk0 
Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print

GPS on Orange Pi 2G IOT

Leave a reply

Recently I got myself a GPS module to play with such as this. Not that I knew much about but felt like something nice to play with. First thing first is connecting the GPS module to the GPIO in Orange Pi 2G. In my case I decided to connect the GPS to ttyS2, asides from VCC (2.8V) and GND. This correspond to pins 1, 6, 8 and 10.
Vcc -> pin 1
GND -> pin 6
TxD -> pin 8
RxD -> pin 10

Pin 1 would be the one just below a small white arrow to the left of the SD card. Below two pictures of GPS connected to Orange Pi GPIO pins.


Another important thing is to cross TxD and RxD cables, that means connecting GPS TxD to Orange Pi RxD and GPS RxD to Orange Pi TxD.
Now that the GPS module is connected to the Orange Pi power it up and log into it. We will now check if the GPS mocule is working, in order to do this we will connect via minicom.

minicom -D /dev/ttyS2 -b 9600

Pepephone 2G on Orange Pi 2G IOT

Leave a reply

Recently I bought an Orange Pi 2G IOT. Pretty decent for $10 I would say, not a lot or RAM or CPU, but the interesting thing from my point of view is the 2G modem. Some pictures below with SIM card installed.


So the idea of this post is how to configure this device to connect to Pepephone network with a PIN on SIM. After some testing I finally came up with below wvdial.conf which works for me.

[Dialer defaults]
Modem = /dev/modem0
Baud = 30720000
Dial Command = ATDT
Init1 = ATE1
Init2 = AT+CPIN="XXXX"
Init3 = AT+CFUN=1
Init4 = AT+CGATT=1
Init5 = AT+CGDCONT=1,"IP","gprs.pepephone.com","",0,0
FlowControl = CRTSCTS
Phone = *99#
Username = " "
Password = " "
Stupid Mode = 1
Auto Reconnect = on

Pin entry above should be replaced with your SIM pin.
Execute running wvdial from cli and you should be able to see a new interface named ppp0. Below is a screenshot of both interfaces ppp0 and wlan0.More info here (in spanish).
