Next, you will set the first ESP-NOW gateway to transmit all serial data to broadcast ESP-NOW: ```#define SERIAL_ACT bufferESPNOW(0);``` This is a somewhat hidden method of sending a broadcast packet using FDRS. If there are other gateways listening for general ESP-NOW packets they will treat these packets as incoming sensor readings, thus this is an imperfect method for larger setups. If anyone knows how to tell an ESP-NOW broadcast packet from a packet that was specifically addressed to the device, please contact me!
## The Future
The next iteration of FDRS will involve a method for devices to send a "ping packet" and connect to the responding gateway that has the best time. Next, the node may send a "pair packet" and the gateway will add it to a list of paired MAC addresses. There will then be a command for the gateway to send data to all paired devices.
