I need some advice on a project.
I want to wirelessly transmit packets of data from a Raspberry Pi to several microcontrollers (Arduino or other). The frequency must be at least 15 packets/s per slave device. I am not really sure about using wifi, as it is usually not very cheap and requires setting SSIDs and passwords manually. Another thing is range. I need around 30m reach.
So far, from my research I have come to only these 2 solutions:
If its the only solution, then wifi
433/ 2.4NRF - RF modules seems to be a nice solution, but I feel there is going to be huge technical problems and limitations
To be honest, I am quite desperate. I can’t find any wireless solution for long, sustainable, reliable, fast transmision of data between master and slaves, simplex. The communication I want to establish is more of a radio transmision than transmitting commands to the slaves.
If you have any recommendation, or can point me to a particular technology that solves this problem, I will be grateful.
One packet contain array of 60 int8 plus short string. Slaves up to 10.
