I am looking for someone that has experience with esp8266 programming.
The master esp8266 will receive serial data (size of 32bytes) and transmit it to all clients.
The slaves are six maybe more in the future. They all have attached a pca9685 chip. (look photo below)
I want code for both the master and clients that send (master) and receive (slaves) the data instantly with very low latency and all slaves must act at the same time.
I have already programmed the chips in micropython but the slaves don't act at the same time. I can provide that code for guidance.
Please contact me with the way you are going to approach the problem.
