Translating code between Lua and JS - buuuudzik - 06.09.2018

Hi,

I am currently translate some code which I've created in NodeJS for controlling Somfy blinds into Lua to use it by LM. Could you help me with translate some functions?

Code:
parseInt(hexValue[i], 16)

toString(16) // e.g. decimalChecksum.toString(16)
And also how can I convert hex string to hex?


Code:
'7FF2FAB843FA000000FFFE065D' => string.char(0x7F,0xF2,0xFA,0xB8,0x43,0xFA,0x00,0x00,0x00,0xFF,0xFE,0x06,0x5D)

Code:
number = tonumber(input, 16)
hex = string.format('%X', number)

Convert hex string to raw binary, make sure second argument is true otherwise zero bytes will be ignored:
Code:
str = lmcore.hextostr('7FF2FAB843FA000000FFFE065D', true)

I've translated whole code and now it produces correct string frame, but I've found some ~bug/~lack in log() function which could be produced by such code:

Code:
S01_up = string.char(0x7F,0xF2,0xFA,0xFF,0x00,0x00,0x8E,0x5E,0xFA,0xFE,0xFE,0x07,0x4C)
S01_up_new = lmcore.hextostr('7FF2FAFF00008E5EFAFEFE074C', true)

log(S01_up, S01_up_new, 'end')


And this is from log():

Code:
* arg: 1
 * string: ���


So it looks that log() doesn't notice the end of first variable.

use loghex if you want to get readable binary strings
