Hello @BwanaFr ,
Thank you for contibuting.
Part of your PR is already addressed in just merged PR #20.
For the other part, can you explain the interest of the static_cast?
ESP32 compiled with latest core 3.3.2 doesn't show any warning.

Hello,

Sorry for the late reply.
If I don't type cast the enum, I get this kind of warning.
SNMP/src/BER.h:289:66: warning: bitwise operation between different enumeration types 'SNMP::Class::<unnamed enum>' and 'SNMP::Form::<unnamed enum>' is deprecated [-Wdeprecated-enum-enum-conversion]

Hello,
With latest core I dont' get this warning.
What platform are you using?

I'm using PlatformIO with pioarduino version 54.0.3.20 (https://github.com/pioarduino/platform-espressif32#54.03.20).
I think this platform enable -Wall GCC option.

Hello,
OK.
May be the best way to solve these warnings is to change from uint8_t to uint16_t Form and Class enums?
Can you try and tell me if it works?

Hi,

I've tested what you propose but I still get the warning message.
Maybe the cast I made (to int32_t) is not appropriate. I think it's more appropriate to cast to uint16_t.

Hello,
Can you try this syntax?

Boolean = +Class::Universal | +Form::Primitive | 0x01,    /**< 0x01 */

Hello,

It works well with this syntax (and it's cleaner :) )

I've updated the PR to integrate these modifications.
Thanks
