If you are asking a question, please follow this template:
-
My goal is: [determine hardware and software limitation]
-
My actions are:
[Hardware : ESP8266 (Fanstel BWG832FX)
Hardware : nRF52 connect UART to ESP8266
Software : Mongoose build using MQTT
Server : [Eclipse Mosquitto in local Laptop ] -
The result I see is: [Using the nRF52 to send data (40 bytes) in UART every 140ms and this packet would then do MQTT.publish in ESP8266. After a few packet is sent, ESP will show “MQTT FIFO overflow” error. If changed the timing from 140ms to 180ms, then FIFO error disappear]
-
My expectation & question is: [Will this be the limitation of this configuration ESP8266 + Mongoose ?? My hope for the project is sending BLE data (20bytes) packet at 20ms sampling rate from BLE sensors.
Is the limitation inside ESP8266 chip or configuration for Mongoose ??]
