Frequently Asked Questions

General

We have specially designed cases for our beacons with different weather, dust and water requirements. You can see them under Products – Cases section. If you need different kind of case – we can make it for you.

Completely backwards compatible with Bluetooth 4.0,4.1,4.2.

By using Coded physical layers (PHYs), receiver sensitivity improves while maintaining the same power draw as in BT 4.0,4.1.4.2. BT 5 uses forward error correction (FEC) to expand payload data bits 1-to-2 or 1-to-4 at data rates of 500Kbps or 125Kbps.

Both high speed and long range is not possible at the same time. Devices can either operate at 2Mbps at a lower range, or at longer ranges with a lower data rate (to achieve maximum range, it needs to be dropped to 125Kbps).

BT 5 does NOT improve delay between packets in comparison to BT 4. It just increases the packet size. This is the reason why the power draw does not increase in comparison to BT 4.

To make use of BT5 high speed or long range, both the central and the peripheral need to have BT5 support. For example, a long range sensors device will not be able to communicate with a phone that does not support BT 5 Coded PHYs.


Support

-.- let’s get serious, beacon only does what you tell him so don’t worry.

We do. Under every product you have all necessary files to get you started working with aconno devices.

We have an discussion section under Developers -> Questions. There you can ask our aconno community for help where our developers answer questions with other developers. If there is no other way, you can reach us at support@aconno.de and we will look at the problem.


Sales

Of course we do. If you ask how much is it – there is only one way to find out – sales@aconno.de

We would be very glad to help you make your device as quickly as possible. You can reach us at sales@aconno.de


Hardware

acn52832 is all you need to start developing low power consumption Iot and Bluetooth applications. The module is equipped with powerful Nordic Semiconductor’s microcontroller nrf52832 which runs on 64MHz. It is so called SoC- System on a Chip- the nrf52832 itself and Bluetooth Low Energy radio in one IC package. So acn52832 is all you need.
acn52832 module is not some kind of modem or Bluetooth transceiver only (like popular HC-05 for example).

acn52832 is a microcontroller with 64MhZ, not a modem, you don’t need other controllers

Tag connect is a special type of connector with tiny footprint.
On our aconno programmers we use Tag connect.
Whereas its main competitor JTAG has much bigger footprint and 2.54mm pitch, Tag connect has pogo-pins
(spring-pins) and 1.27mm pitch.
Tag-Connect cables are currently available in two versions: ‘Legged’ (TC2030-MCP) and ‘No Legs’ (TC2030-MCP-NL). Both have a Tag-Connect connector on one end, and an RJ12 (6-pin modular plug) on the other directly compatible with Microchip In-Circuit Debuggers and Programmers.

The CR2450 battery relies on the same storage technology as the CR2032 type. Therefor the energy density is the same, but hence the CR2450 cell provides more capacity due to its larger size. The capacity also varies between manufacturers and lies around 620 mAh.

The capacity varies between the different manufacturers. In general the capacity of the coin cell is around 230 mAh.


Firmware

The Segger Debugger and Performance Analyzer. It allows you to debug through the code.

Thereby it also contains a lightweight text editor.

The SoftDevice is the firmware required to have with each Bluetooth application.

It provides a low-level API over Bluetooth and other capabilities of the chip.

Here is how the application communicates with the softdevice: the SVC calls (each of which has a different number) trigger the SVC IRQ handler which the softdevice implements and performs the requested action. This is why you don’t have to link with the softdevice, there’s nothing to link with, the entire communication between the two is done with SVC calls. That’s also why there’s no .c file, there’s no C, apart from the SVCALL() macro which expands into 2 lines of assembler which call the SVC call with the correct number and return.

All examples made on mbed.org platform have already included Softdevice (if Bluetooth is used).

Firmware development in other IDEs requires to program softdevice into chip manualy. More on Softdevice fine here:

Mbed is an online platform that provides everything you need to develop IoT devices and applications. It provides full support for over 100 “Mbed Enabled” boards and more than 400 components, tools for writing, building and testing applications.

To develop with aconno modules or aconno DKs you needs to register on mbed.org as developer and choose Nordic nrf52-DK as target development platform.

Many examples to work with aconno boards can be found on official aconno dev team mbed web site: https://os.mbed.com/teams/aconno-dev-team/

All the examples can be easily tested with few clicks. You should first click on Import option to import an example into your Arm Mbed Online Compiler. After it, click on build and compile options. After building and compiling process you get your hex file. The hex file needs to be uploaded on aconno boards using simple drag ‘n’ drop.

Restart aconno board to see your first program in action.

Here’s the link for step-by-step introduction tutorial:

Yes, possible.

Use their manual to install the mbed-cli: (https://os.mbed.com/docs/latest/tools/installation-and-setup.html)

Then set:

         mbed config -G

         Use for example in linux: mbed config -G GCC_ARM_PATH “/usr/bin”

         -G flag makes settings global

Use that command to:

          GCC_ARM_PATH

          TOOLCHAIN GCC_ARM

          TARGET NRF52_DK

In the end check with

          mbed config -L

Clone repos with

          mbed clone

Compile with

          mbed compile

If there is a error with the libs and you get prompted to use “mbed deploy” and it does not work, try to delete all folders which have a *.lib with the same name. Then run “mbed deploy”.


Software

No, only the sky’s the limit. 🙂

We have wide variety of our products using Bluetooth, NB IoT and other connectivity technologies. It all depends of your needs. If there is something you don’t see and you need, contact us on info@aconno.de and we’ll make it work for you!

Yes. After you setup your beacon, you can close your app and when necessary open to interact with it.

Yes. You have to activate aconno beacon, tell him what to do and then you will have one more happy and functional beacon 🙂

You can find our app very useful for getting started with our devices. For more informations please go to our Products – Application section
