QUESTION
Looking at the source-code of the Arduino-Ethernet-Library I found this:
...ANSWER
Answered 2021-Oct-13 at 17:40The performance improvement is not significant, although in an arduino environment, you may be fighting to reduce every byte of generated code (more than execution speed).
As listed, the code is a bad idea, although it will "probably" work OK, that's usually not good enough.
For this case, you could do something like this:
QUESTION
I use the bluepy
module to connect to an Arduino board with BLE running a battery monitor.
My Python script is working perfectly fine. I get the values I expect. But I do not like the solution because the binary value read from the characteristic is interpreted as an ASCII character before getting the decimal representation of that ASCII character.
I tried to use the binascii module
...ANSWER
Answered 2021-Aug-26 at 14:22The characteristic read is returning bytes e.g b'/'
. If you want to convert that into an integer then the int.from_bytes()
functionality is useful. e.g:

QUESTION
I'm using this simple ArduinoHttpClient example code to send a sample POST request from my Arduino to a publicly accessible URL. It works. I get a legit response.
But now, I want to send a HTTP request from my Arduino code that mimics this curl call to send an email via MailGun:
...ANSWER
Answered 2020-Apr-18 at 06:30With ArduinoHttpClient library the Authorization header is created with sendBasicAuth
. The example for function sendBasicAuth
is in BasicAuthGet example of the library.
client.sendBasicAuth("username", "password");
Background: the HTTP header Authorization value of type Basic is a Base64 encoded concatenation of login and password.

...ANSWER
Answered 2020-Apr-14 at 05:43You can just call the curl command from c++ by using the system() function. Ex:
