ESP8266 wifi telemetry — Copter documentation

Tried to flash it with code above but no luck.

I use ESP8266 radios on a few models. They work great. The ESP-01 version that cost ~$1.

The PX4 reference doc is useful for these el-cheapo modules:
ESP8266

Do you recognise the model on the picture?
It seems it has not boot-loader at all. I want to flash it with original first to make it working.

Got it: NodeMCU v3 it’s ESP8266 not ESP32…

Let play so …

Yea, it’s a breakout board for the ESP8266 chip with USB support. But this is really all you need:

Got your point but have two of them.

It was easy, as for first time with ESP8266

Can’t get it running. I lack sufficient knowledge in MAVLink connections using TCP/UDP

Edit: Running !!

@dkemxr What range do you get from it in the air?

9

………………………

100m max range. No doubt you could do better with an external antenna.

10

Do you experience connection issues??
My board is hit by GPIO1 Low issue so I have to power it up first then connect TX …

GPIO 0, GPIO 1(TX) & GPIO 2 should not be pulled ‘LOW’ at boot, that means anything you connect to those pins as an output, should be connected ‘Active LOW’

This equipment can be used with the Ardupilot. I made a video of how you can do it. Installation of telemetry for the Matek-743 WING flight controller with a Wi-Fi ESP8266 module on the Ardupilot platform.

Thank you!
I made it running but have to tweak code a little.
Serial port has to be moved to other pins to avoid GPIO1 LOW lock on boot.

It was strange it was included in the code but commented out by debugging define

Could be author used to debug all the time or had other board.

That appears promising.

You might want to try out this one: GitHub - DroneBridge/ESP32: DroneBridge for ESP32. A secure & transparent telemetry link with support for WiFi and ESP-NOW. Supporting MAVLink, MSP, LTM or any other protocol

I got it working on very small SpeedyBee BT Nano, and that supports not only WiFi, but also ESP-NOW which has lower bitrate (~250kbps AFAIR), but longer range than WiFi.

Can’t make it working on my ESP32.
While that one works perfect…
