Reply To: ESP-01 connection drops in metal cold room cabinet, external antenna options

Thanks a lot, Kerem. We fitted two rooms with ESP-07S and external antennas, RSSI is -63 / -66, and there have been no drops for two days. I also set the offline timeout to 600. The technician forgot to pull GPIO15 to ground while flashing the ESP-07S, and we struggled with it for half a day, so I’ll mention that too.
