I am new to raspberry pi zero and I want to connect it with gsm module for gprs connectivity .
I bought sim800a gsm module but its led not even blinking single time
I am able to turn on the UART on pi zero and coonect it over usb cable through ssh .
Can anyone help me out how to achieve what I want and also suggest a better gsm module for gprs if sim800a is not good enough

I'm trying to read a signal from a magnetic sensor then want to send it over BLE to a Raspberry Pi 3 module.
What device(s) can I use for the BLE signal reading / transmitting and how do I pair it with a Raspberry Pi 3? Did anyone else try doing this?
There are a lots of modules that you can use for transmitting over bluetooth, SimModules and Hc Modules are two of them. Sim modules also support GPRS and 2G networks. both of them works with At Commands and it can be controlled by a simple MicroController like Arduino series.
what I want to do :
use Raspi zero & wifi dongle to build a access point, so that other device like smart phone or PC can access to rasperry pi directly.
image in my mind is like this :
internet >> wifi router >> raspberry pi zero >> other device
what I used:
raspberry pi zero
WIFI dongle buffalo wli-uc-gnm2 (http://buffalo.jp/product/wireless-lan/client/wli-uc-gnm2)
I follow these processes:
use rasp-pi 3 as access point
use rasp-pi 2 and 2 wifi dongles as a router (http://qiita.com/mt08/items/4247894833bd4dcb27e2#_reference-27aa37c4be7f602667ff)
In the 2 instrument, with 2 dongles raspi can link to the wifi router, at the same time be an access point.
My question is can I use 1 wifi dongle to do the same thing, since buffalo wifi dongle has the ability to be AP and like to wifi router at the same time, but I cant find the instrument their site, the driver is only for windows PC.
any advice for linux environment todo that ??
I don't know if it's possible to achieve this with only 1 wifi dongle and I'm not even sure if it's possible with 2 since the only way I am aware of to set up a Pi as an AP is to connect it to your router via Ethernet and connect devices to your Pi via Wifi. But either way, isn't it possible to use a usb-hub on the Pi zero and then use 2 Wifi dongles or 1 Wifi dongle + Usb to Ethernet?
And to set up things I'd recommend: https://www.maketecheasier.com/set-up-raspberry-pi-as-wireless-access-point/
Hello my name is Edris,
I am looking to make a connection between a raspberry and 2 arduino's with bluetooth. So the raspberry pi 3 would be the master and the arduino's slaves.
But then I thought mayby is it easier to have two connections at the same time.
So one with the build in bluetooth chip
and the other
with a usb bluetooth stick.
The bluetooth chips are all BLUE LoW Energy. Also the build in chip in the raspberry pi 3
Looking forward to hear from someone.
Edris
here are a couple of ways to connect
my preference is bluetoothctl. you'll be able to control each dongle by it's ID, given its ID appears when you do scan on and a list of IDs prints
I am able to connect sensors using the GPIO pins.
My Question is:
Is there any possible way to connect any kind of sensors to the raspberry pi via Bluetooth or wifi?
And get the data via the same!
If you want to do it with any kind of sensors. I should be:
Sensor -> Micro-Controller <- Bluetooth/Wifi Module )))))))))))((((((((((( Bluetooth/Wifi Module -> Raspberry Pi
I am trying to send/receive data over serial connection (GPIO UART pins) between a Raspberry Pi (B model, raspian wheezy) and any pc (tried a netbook and desktop, both running with win 7).
I followed all the stepts found in several tutorials like: http://codeandlife.com/2012/07/01/raspberry-pi-serial-console-with-max3232cpe/
to build a 5V to 3.3V converter. (unfortunately i can't post a pic yet)
The settings for ttyAMA0 in files 'cmdline' and 'inittab' are ok. (like described in many tutorials)
Connecting RX/TX on rpi direct works fine, so i can send text over GPIO pins and receive it. But as i connect it to a pc there is no way to read or write any data. Baudrate 9600 or 115200 doens't matter. (Hardware connection: rpi GPIO -> voltage converter -> serial USB adapter -> pc)
On pc i used Putty. On the rpi:
'echo text >> /dev/ttyAMA0' on the terminal
Putty and
minicom
but no one had success
Is there anything i missed? Could you give me some advice i could look for please.
some ideas:
Whereever i plug the usb into one of 3 available netbook USB ports the win device manager always say it's on COM3... shouldn't it change?
is there a possibility to make some measurements inside the voltage converter wiring to insure that it's not a broken component in the hardware circuit? (i have no knowlegde of it's function)
