SP511-E - 'WLED-AP' not showing up

WazzA1987 · August 19, 2023, 11:38pm

Hoping someone could help.

Have flashed ESP8266 (SP511-E) successfully a few times but nec\ver does the AP show up on my Pi or iPhone.

Thanks to this guide so far:

## Installing WLED on SP511E Controller

The SP511E addressable LED controller is the successor to the very popular SP501E controller. It is available for around $8 
on [AliExpress](https://www.aliexpress.com/item/1005002944086008.html?) and $12 on [Amazon](https://www.amazon.com/WS2811-WS2812-Controller-Bluetooth-DC5-24V/dp/B09CGNWDWF/). 
Like the SP501E, the SP511E is powered by an ESP8285 with 2MB flash running a firmware for the FairyNest app. 
Unlike the SP501E, the SP511E comes with an IR receiver and 38 key remote, 3 case push buttons, two output connectors (on same pin), 
and a microphone. Both the SP501E and SP511E controllers are quite capable, however FairyNest leaves much to be desired. 
It has 180 dynamic effects, however they are mostly different color combinations of perhaps a dozen animations. 
And before you can use the app, you have to register with your email.  

#### Firmware
To make better use of these controllers, we will be replacing the stock firmware with [WLED](https://github.com/Aircoookie/WLED).
WLED is open source and features over 100 animations and 70 color palettes, a large number of interfaces and is very configurable.
There is also a Sound Reactive fork of WLED. Because the FFT calculations require the additional processing power of the ESP32, the Sound Reactive
WLED community focuses their efforts there. The EPS8266 version does not have 2D matrix support or FFT effects, but it does have
over a dozen (volumetric) sound reactive animations in addition to all the effects in standard WLED. 
The last Sound Reactive WLED version that supported ESP8266 chips was 0.13.0b-3.
Since then, many of the features of the Sound Reactive fork have made their way to WLED 0.14. The WLED 0.14 version adds 2D support, numerous 2D effects and sound reactive effects (The effects will play but will use simulated noise instead of your microphone.)
The main SR developers have committed to getting volumetric effects working on ESP8266s again. But for now, you have to choose between having a working microphone and having the latest version.

Any ideas how to go about troubleshooting? Below copy of the cli output from most recent flash. I have soldered on all all uarts and kept the soldered ‘io0 to ground’ active - trying to avoid too much back and forth, maybe this needs to be removed?

Appreciate any guidance.

Well, after leaving the unit disconnected for a few hours, I can now login as normal after f\removing the soldered uart pins.
