B4R Question ESP8266 Serial Speed

[Bert Oudshoorn]

Is AsyncStream slow? I echo a byte to a PIC microcontroller, which echoes it as well.
It takes about 5 msec to receive and return a byte at baudrate 115200
Baudrate 9600 is only about 25% slower. Used an esp8266-01

In the Arduino IDE, there is no sketch example, to test/try it in C.

Set AsyncStreams.WaitForMoreDataDelay to 0. The default value is 5ms.
The purpose of this delay is to pass complete messages.

Thank you, reach now 200 usec per send-receive = 100 usec per 8-11 bits = bruto 80.000 - 110.000 baud (whether start-stop-parity bits are included?) Not bad! The PIC (16F688) is "only" 20 Mhz.
By the way: Switching Wi-Fi (Access Point mode) On or Off had no impact on the speed (without UDP traffic).
FYI: Programmed the PIC with the Pascal-like JAL (Just Another Language)
