There was a bug in the version of wpa_supplicant Farmbot OS uses relating to the Raspberry Pi’s wifi chip driver. (brcmf_mac) along with FarmBot not being properly notified when disconnected. (that is disconnected from the access point)
The exact reason is being logged, it will just never make it to the backend services since FarmBot is disconnected. This is why i built the feature to capture all previous logs.
There is also a bug in that after a reconnect, those logs will never actually make it back to the backend services. Rick and I have been working on a solution for this, but it is actually a really complex issue not just limited to logging.
Farmbot has a huge disadvantage that a user can only indirectly communicate with Farmbot. (IE it needs to be connected to the network, and a user needs to be connected to a network etc) It is similar to ChromeCast, or similar devices. Unfortunately we don’t have the same development team that Google has
