The uncompensated temperature of the BMP180 is incorrectly converted to a 16-bit signed value, instead of a 32-bit signed value (long). Since the data is 16-bits wide and can therefore not be negative, the easy fix would be to do the following:

sip.js(1128): uncompensated = uint16(data[0], data[1]);

Please see page 15 of the manual of the BMP180 chip:

Problem

emberPrint() is used by the ZCL code to build up a log entry, which is "finalized" by a emberPrintln(), but CHIP cannot assume single-threaded access to logging that this model requires.

Proposed Solution

all the places that use this model (emberPrint()+ .. emberPrintln()) need to be coalesced into a single emberPrintln()
