BLE scanning not picking up MAC address

Hi guys,

Looking for some guidance as I am having issues with the BLE scanning MAC address feature in the Argon products. Specifically, from what I can tell all these Argons are running the same code, but only one of them is successfully picking up the desired MAC addresses which is hardcoded into the main.ino. The rest of the Argons do not pick up any of the MAC addresses we need them to find.

The Argon that is successfully picking up the desired MAC addresses is currently running DEVICE OS 3.0.0. The other Argons which are not picking up the MAC addresses are running DEVICE OS 3.1.0.

Could the different device OS be the reason that explains this behavior? If so, how can we fix it and have all the Argon successfully pick up the desired MAC addresses when scanning?

Cheers,

Seb
