I made 2 orders on Banggood:
On the First order, I bought 2 items:
A few days later, I decided that I would like to have another Mega2560+Wifi,
so I made a second order, which included only 1 item - the Mega2560+Wifi.
those are Arduino compatible boards, that have an ESP8266 module built in.
They look like this:
Both orders arrived.
Verifying the Uno+Wifi board works well:
I connected the Uno+Wifi to the PC,
and opened a Serial Monitor,
(and made sure the DIP Swtich on the board is set to USB<->ESP8266 Communication)
And what I get is a program that is running on the ESP8266, that lists the visible WLANs in the area.
In addition, the ATmega328 on this board is running the program Blink.
So in short, the Uno+Wifi board is working well.
Verifying the Mega2560+Wifi board works well:
I then went on, and connected the Mega2560+Wifi to the PC,
opened a Serial Monitor,
(and like before, made sure the DIP Swtich on the board is set to USB<->ESP8266 Communication)
I see jibrish, on 9600baud,
and when I change to 115200baud, I still see jibrish.
Because of this, I decided to checkk all possible baudrates,
at least all the ones that the SerialMonitor enables me to choose.
Here are the results:
As you can see,
I tested all possible baud rates, and in all we get jibrish,
just in different length…
When I saw that it’s jibrish in all baudrates, I thought that the Mega2560+Wifi board arrived defected…
But the problem is, that today I received my second order, which contains the second Mega2560+Wifi,
and it behaves exactly the same…
Jibrish in all baudrates
So now I start to think that maybe the first (and the second) Mega2560+Wifi boards are not defected…
If so, what is the problem, why do I see jibrish?
Thank you for your help
