It seems that interrupt function is called with UART class parameter, on which I can call function any() ( it does not work with read() ).

CODE:

>>> def irq_fun(obj):...     print("Type: ", type(obj))...     print(obj.any()).........>>> uart2IRQ = uart2.irq(trigger = UART.RX_ANY, priority = 1, handler = irq_fun, wake=machine.IDLE)>>> Type:  <class 'UART'>105Type:  <class 'UART'>112Type:  <class 'UART'>119Type:  <class 'UART'>126Type:  <class 'UART'>133Type:  <class 'UART'>140

i made some weird one that is working. after calling ISR callback set sleep for 5.1ms (depends on your baudrate,, this one is for 9600), then read the rx with uart.any() > 0, uart.read()

this halts the mcu for 5.1ms, but working. im sure that there is better solution.
