A6 GPRS Module Quad band

I got my A6 development kit the other day and I most say I am impressed.
The A6 Modules are “EXPENSIVE” well when I say expensive they are 3 times as expensive as the cheep (now apparently second hand modules) available from ali-express @ a hefty $US4.20 delivered. Well this is definitely a case of you get what you pay for. The Sub Module contains a proper MP1584N power controller ic. A Real aerial which gives me good indoor reception as opposed to the 3bars I get on my phone.

The manual is a bit Chinglish but I converted the module docs to english with google translate.

If you buy the Dev Board which I did you actually get a “phone-lite”, you can make calls and send test texts. It comes with a graphic dot matrix display and a keypad all powered by a 8051 powered STC processor. Oh and you get all the source code. It comes with a CH340 USB to serial Chip you can monitor it as it sends texts and makes calls. If you flip all the dip switches to the opposite positions, I.E. 2,4 on and 1,3,5,6 all off, you can control the module directly with termite (115200b/s). I used the Dev board to get familiar with the modual and its great for that.

The sub module has a micro usb connector to power it with a phone PSU etc. Also the 5vUSB is connected to the 5V pin on the DIP connector so you could use that power connector to power your whole project. :) I used one of those cheep usb power meters to test the consumption of the module. After 3 hours of messing around it had used 12mAh. Most of the time it doesn’t register any power it peaks to 60/70mA when sending a text. And about 20mA when messing around with GPRS.

It has a few really nice features that you may not have considered usefull.

1/ A real time clock that is set by the network it also knows its Time Zone.
2/ 15 alarms yes 15 all with repeat function so you can set an alarm for 12 Noon and have it repeat Every day or every weekday etc. The alarm also powers the module on so for say a AMR system you could set the alarm for midnight each day the module would power up send +CALV: <n> to the controller the controller could then tell the module to send the data as a text and power the module down. Which can also be done by a single AT Command.
3/ A low power mode <1mA. All functionally still works SMS phone e.t.c. but the AT command serial is off this is controlled by pulling a single pin low.

I have So far managed to.
Make a call
Receive a call with CLID (Caller Line ID) Cnam is not passed by my carrier this is standard in the UK.
Send a Text
Receive a Text
View Edit the phone book on the SIM.
Set an alarm and wake the module.
Look up a DNS Address.
Establish a TCP data connection to my SSH server. Note you cannot establish a TCP connection to a domain only an IP Address.

Below some typical output.

It looks like AI are expanding their range the new A7 is going to have built in GPS no pricing yet. And the A6C will have camera input.

Add a camera and voice / data internet to a project for about $12. It says you can access the camera via AT commands. I will probably buy one an have a play.

Looks like the A6Cs are shipping

that discrepancy got my attention as well, i’ll no doubt be looking for a separate aerial … …
i wonder if the aerial you get is random? so if you buy 2 odds of one of each are what?

the test set i’ve also ordered has both in the photo and a module as well, i’ll see how well that pans out … …

I’ve received my A6C last week.
Unfortunately, although at power up, it display things at proper 115200 baudrate, I’ve tried AT and ATI commands with both CR-only and CRLF and never responded to my commands. Maybe it doesn’t because I didn’t have any SIMM card inserted yet, but I would like at least test the camera ?
I presume I will have to open a dispute.
