New W01 OEM module not reading the CAN line

[mjmillere80]

(sysname='WiPy', nodename='WiPy', release='1.20.2.r6', version='v1.11-c5a0a97 on 2021-10-28', machine='WiPy with ESP32', pybytes='1.7.1')

Steps to cause this issue:
1. We built another run of our product with your W01 OEM modules
2. We programmed the W01 modules with the same program as our previous run
3. Tested the units
What we expected:
We expected the new units to read the CAN line of a small engine and perform just as the previous run of units.
What happened instead:
The units will not read (receive) the CAN line

We found that any unit with a MAC address starting with 240ac4 will work just fine. Units that start with c8c9a3 will not work. Even when using the current examples in the documentation.
