testing firmware on blank Arduino Micro

Hello Plen2 team,

first to say: Plen2 is the most beautiful mini robot i've seen, my son will love him. Domo arigato, Mr. Roboto!

I've uploaded the firmware to a naked Arduino Micro to make some tests.
Firmware is well structured using classes, separate units and easy to understand namespaces.
Well done!

1.) Plen2 doesn't say: "Hello my name is Plen2, my system is up and running firmware 1.xx, let me walk!" This would be very helpful to test

2.) <vi command does nothing?

3.) Enabling DEBUG: "xxx in fuction" should it be "xxx running in funCtion"?

4.) It's unclear how USB-/BLE serial work together. When i connect a BLE serial shield i can communicate via both connections?

Thanks so far
Best regards
Dirk

Re: testing firmware on blank Arduino Micro

Hi, Tueddy.

Thank you for your cheering! We work for people get more fun through PLEN, always have, always will :)

1.) OK, I'll think about this.

2.) No, "<VI" command has implemented since firmware version 1.1.0. For example, I have installed firmware version 1.2.1 to my PLEN2, and then send the command, I can get json like below.

```json
{
    "device": "PLEN2",
    "codename": "Cytisus",
    "version": "1.2.1"
}
```
I thought that you are not using PLEN2's baud-rate. PLEN2 and other component to communicate with baud-rate of 2,000,000.
(It's defined here: https://github.com/plenproject/plen__fi … .h#L37-L41)

3.) Oh... I had not noticed the typo X(  This bug has fixed currently, please check below.

4.) That's right you intended.

Thanks Guvalif for explaination!

Typo is fixed, perfect!
My baudrate seems to be wrong, but in Arduino IDE i cannot set to 2,000,000? Max value in serial monitor is 250,000 baud.
Is there a line like Serial.begin(9600);? I did not found it..

Hi,

> ... but in Arduino IDE i cannot set to 2,000,000?
Yes, we use other terminal emulator to communicate with PLEN2. (In japan, the most popular one is Tera Term.)
If you want to use other baud-rate, please change their definition that described before, or write "Serial.begin(xxx);" directly in the setup().
(By the way, the firmware calls Serial.begin() at here.)

If you are interested, let get the additional information why we are using baud-rate 2,000,000.

Re: testing firmware on blank Arduino Micro

Hi Guvalif,

thanks now i see! <vi works and i can upload motion with latest motion installer for win.
I'll try a bluetooth HM-11 BLE 4.0 module because BLE113 visual is not available in germany.
The HM-11 is cheap and seems to work with iOS. I'll report back here if it works.

Best regards
Dirk
