…but only in the best situation.
On SF7, one can send about 222 bytes each time, which then takes 368.90 ms and allows for only 81 such packets per day. So then it’s a 17,982 bytes image, assuming all packets are received well.
For SF12 it’s about 51 bytes per message, 2,793.47 ms, maximum 10 packets, hence 510 bytes.
Don’t try this.
