I'm having trouble reading the accel and gyro data from a websocket. The default /firmware-c web interface gives a link to the CSV file, but I'm getting 0 bytes or "unable to connect" errors at /d/fastacc.csv

I'm able to create websockets to these endpoints I found in the source:
/d/ws/echo
/d/ws/evaltest
/d/ws/issue

My hunch is I'd have to create a new endpoint: /d/ws/fastacc which the ESP sends websocket packets to connected devices through.

The web interface and fastacc() in /firmware-c/user/user_main.c looks like the device should already be sending this data, I'm not sure the endpoint to connect to or if this is a problem with my setup.

When I click on the Fast Acc CSV link in web interface, this function should write to socket. 'Save link as' doesn't make a difference:

static ICACHE_FLASH_ATTR void fastacc()
{
	//char mydat[128];
	//int len = URLDecode( mydat, 128, curhttp->pathbuffer+8 );

	char buf[1024];
	int times = 20;
	int len = 0;
	int16_t data[10];

	if( first_acc == 1 )
	{
		first_acc = 0;
		len += ets_sprintf( buf+len, "gx, gy, gz, ax, ay, az\r\n" );
	}

	for( ; times > 0 && lsmhead != lsmtail; times -- )
	{
		int16_t * data = &lsmdata[6*lsmtail];
		lsmtail = (lsmtail+1)%LSMBUFFERSIZE;
		
		len += ets_sprintf( buf+len, "%d, %d, %d, %d, %d, %d\r\n", data[0], data[1], data[2], data[3], data[4], data[5] );
	}

	if( len )
	{
		START_PACK;
		PushBlob( buf, len );
		END_TCP_WRITE( curhttp->socket );
	}

	if( i2cmode == 0 )
	{
		curhttp->state = HTTP_WAIT_CLOSE;
	}

}

I would like recreate this device but the hardware section is missing the pcb file. Could it be included in the repository?

Cloned esp82XX-basic example compiled and flashed to esp without issue. Everything works great.

Unable to do make all in /esplocalizer/firmware-c, compiler missing 'lib' files. What does libmain.a do and where can I get it :) ?

Hello @cnlohr,

Thanks much for publishing your projects as open hardware as well as the firmware, always inspiring stuff to learn from you.

I have been trying to reuse your .sch since I have a couple of modifications in mind to your design.

Sorry if this sounds obvious (I'm a relatively new KiCad user), but how can I auto-import the footprints for pcbnew without manually importing each .pretty library/module? as the KiCad docs state, i.e:

https://github.com/jdunmire/kicad-ESP8266

I thought about giving this giant meta-pretty-repo a shot, but the ESP footprint doesn't seem to be there:

https://github.com/monostable/kicad_footprints

I understand you might be using your existing installation/footprints from past projects, but what would be your advice to semi-automate this process of importing footprints?

When I build esp_10dof.ino using Arduini 1.8.5 I get the error:

How to fix it?

New install following instructions, cloned esp82XX-basic example, successfully flash firmware with "make burn" and "make burnweb" (no errors), but doesn't start a wifi hotspot. Serial output on reset shows:

esp82XX Web-GUI
Version: v0.1-7-g06742-dev - Build Thu Jan 19 20:05:33 PST 2017 with -DICACHE_FLASH -DWEB_PORT=80 -DCOM_PORT=7777 -DBACKEND_PORT=7878  -DSLOWTICK_MS=5Loading Settings: af / 0 / 69 / 69
Settings Loaded: ESP_930A72 / Default

Boot Ok.

I'm not sure how to debug why the Opmode would be 0 (wifi off) for this example project. Any pointers would be really helpful, thank you!

On MacOS 10.12

Can you please expose more information on the parts you used? Especially the LDO you used.

Is it < 20 uA?
That would make it a really useful IoT device.
