Note – there’s currently a 300 byte payload limit on Spotter messages (This is not enforced in the Motes and is not well documented anywhere currently, so you would just see an error in your Spotter if you tried to send something larger than this - cc @zachary).

Ah! Thanks for the heads-up @evan! I just looked into this, and the reason is that we add a 29-byte header to the message encoding things like device health and location, which means the precise limit is 311 bytes. I just verified this. If I call spotter_tx_data with 311 bytes, it sends just fine, but if I call it with 312 bytes, then I get these messages in my Spotter serial console.
