- Sun Jul 10, 2016 3:48 pm #50524 I have used SERIAL_RX_BUFFER_SIZE in esp8266 cores HardwareSerial....
Since I upgraded to 1.6.9 I cannot find this and don'tknow how to change the Rx size....

Can anybody tell me how to increase the Hardware Serial RX buffer size to 1024 in Arduino 1.6.9 ESP8266

- Sun Jul 10, 2016 3:54 pm #50525 Your version uses the hardware buffer of the ESP (128 bytes). In the latest git there is a software buffer added back and defaults to 256 bytes. It's size can be changed with

Code: Select allSerial.setRxBufferSize(1024);

for example. The return will be the size of the new buffer or the size of the old one if it can not allocate the size you requested.

With 2.3.0 xx I'm getting........................
