I also think so, but I never used MP on esp.
Maybe you could create an issue on GitHub. Please try to search through existing issues first, there are several related to MQTT client.

I experience something similar on CC3200 port when trying with MP version older than 1.8.x.

This scanner was created during a hackathon with modules from our laser 3D controller project and won first place ;-) https://drive.google.com/file/d/0B2mvAuXuxQ6Bc29lTFo1aW1sck0 It can display time, temperature measured from SHT31D sensor and when nearby person is detected by PIR sensor, it zooms d...

@pythoncoder, I wanted to implement your solution, however enumerate() probably does not work with list of lists as expected: >>> alphabet["A"] [[0, 0], [1, 4], [2, 8], [3, 12], [4, 16], [5, 20], [6, 24], [7, 28], [8, 32], [9, 28], [10, 24], [11, 20], [12, 16], [13, 12], [10, 12], [6, 12], [13, 12],...

Dave, it helped, thanks a lot! Decorator @micropython.native increased performance of my function by almost 10%. I am looking for further improvements. This is my code - its purpose is to render words consisting of letters - each represented by 20-30 X-Y coordinates defined as two-dimensional lists ...

I was not able to build MP with MICROPY_EMIT_THUMB and MICROPY_EMIT_INLINE_THUMB set to (1) CC ../py/compile.c ../py/compile.c: In function 'compile_built_in_decorator': ../py/compile.c:759:24: error: 'MP_QSTR_native' undeclared (first use in this function) } else if (attr == MP_QSTR_native) { ^ ../...

Thanks Dave, I will rebuild tomorrow and check if it works.

Could you please suggest some typical test function on which I should observe improvement when defined with @micropython.native or @micropython.viper decorators?

When trying @micropython.native or @micropython.viper decorator on MicroPython v1.8.4-54-gec078af-dirty on 2016-09-22; WiPy with CC3200.

Do I have to enable it manually somewhere before building MP?

Why in case of WiPy the heap size is less that quarter of total RAM size, when for other boards it is around half of the RAM size?

Are there any options how to build the CC3200 MP port with bigger heap size?

Reading UART data to bytearray through ISR did help. It is easier when messages are up to 8 bytes long.

Anyway I think there must be some memory leak. When not printing anything and reading UART within main loop, received data are often mixed with some other data.
