HTTP requests causing system to crash and reboot

Running Espruino 1v99.175 on an ESP32

This is the same result when I try any of the simple HTTP request examples on the site.

Interesting... of course annoying for you...

What about the power supply? Unstable power supply can cause reboot.

Browsing the Web bubbled this 6+ months old thing up: https://gitlab.com/painlessMesh/painlessMesh/issues/221

It's not core 0 but core 1 and it's not Espruino but Arduino... nevertheless it is a thought worth. @JumJum has done quite some work on ESP32 and things may ring a bell for him...

Did you turn off bluetooth? It frees up some resources on that version particularly.

ESP32.enableBLE(false)

-=h

I tried v1.98 which works fine and v2.0 and up work although there is an issue with the WiFi module saying

ERROR: Wifi: event_handler STA_START: esp_wifi_connect: 12298(SSID is invalid)
WARNING: Wifi:startMDNS - espressif

Although the connection is in fact successful

I'm using v1.98 for now because it doesn't crash on requests and doesn't have this WiFi issue.

How do you use that? I get an error.

It showed up only recently, but probably is in 1v99 for sure:

http://www.espruino.com/Reference#ESP32

ESP32.enableBLE ⇒

Call type:
ESP32.enableBLE(enable)

Parameters
enable - switches Bluetooth on or off

Description
Switches Bluetooth off/on, removes saved code from Flash, resets the board, and on restart creates jsVars depending on available heap (actual additional 1800)

Note: This is only available in devices with Bluetooth LE capability

Gordon wrote this nifty trick on how to check an addition in a different post a while back. If one clicks on the right facing arrow, adjacent to the heading ESP32.enableBLE at:

http://www.espruino.com/Reference#l_ESP32_enableBLE

which hyperlinks to the GitHub source, L123

https://github.com/espruino/Espruino/blob/master/targets/esp32/jswrap_esp32.c#L123

That file edit date is 46eceda on Jun 8, 2018

Now if I could only find the chronological running edit detail for versioning . . .

EDIT: Ahhhh . . . here it is:

https://github.com/espruino/Espruino/releases

1V99 was on on May 22, 2018

Not definitive, as I'm not sure if one can fetch data on older releases to determine the actual inclusion date, short of d/l the referenced .zip and doing a lookup that way, or running through each pull request.
