I noticed that the wifi module ESP8266 was used by some members of the forum. But not together with the MPU9250. That says at least my search.
I came up with this idea because I think about two connected Raspis. The first is to house the main server with external connections such as wifi, mqtt (iot), gms and connect additional sensors (temp, motor, tank, ...). The second should mainly / only manage the MPU (may be some other sensors). I wonder if it really is neccessary to use a grownup Raspi in this location.
1. If two OPs are involved. How are the calibrated compass values, for examlpe via SignalK, distributed to the second server? (MPU - server - server case)
The idea behind this is also to have a backup if one server fails.
2. Question about the software: Is it possible to send the MPU data via i.e. TCP to OpenPlotter, using OP's calibration funktionality? (MPU - wifi - server case)
I would be happy to hear your expertise.
p.s.: I'm testing by myself. But I damaged one of my two Raspis and have to wait for replacement.
