wifi connection regression in 1v95?

[espruino-discuss]

Posted at 2018-01-14 by DrAzzy

After flashing my ESP8266's, I do (ccharacters enclosed in <> are nonprinting chars - that's how hTerm represents them when you copy/paste):

var wifi = require("Wifi");<\r><\n>
wifi.connect("TwilightZone", {password: "ThePassword"}, function(err){if(err)console.log(err);else console.log("connected!");})<\r><\n>

Then once it prints connected, I do wifi.save() and power cycle the ESP8266 and see if it has an IP with wifi.getIP().

Under 1.94 this works on my WeMos D1 Mini.

Under 1.95 it does not.

When I give the command to connect, and it triggers the callback, instead of "connected", I get:
<\r><27>[Jconnected!<\r><\n>
(where <27> is ascii char code 27 aka 0x1B).

Note the extra CR, non-printing char, open bracket, and capitol J.

But it gets an IP and seems to work - until power cycle.

After powercycle, it does not come back, and I cannot connect to that network again (haven't tested other networks) until I reflash the ESP8266.

Are other people seeing this behavior?

It takes some seconds to connect the AP

Steps I do to have a working wifi after reboot.

get official zip for 1v95, unzip and change to directory espruino_1v95_esp8266_4mb

list of files:

1122 15 Dez 12:59 README_flash.txt
4096 15 Dez 12:59 blank.bin
3856 15 Dez 12:59 boot_v1.6.bin
128 15 Dez 12:59 esp_init_data_default.bin
509332 15 Dez 12:59 espruino_esp8266_user1.bin
509332 15 Dez 12:59 espruino_esp8266_user2.bin
2961 15 Dez 12:59 wiflash.sh

first erase

esptool.py --port $COMPORT --baud 115200 erase_flash

than flash

esptool.py --port /dev/cu.usbserial --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB-c1 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin

result after flash

now setup wifi, save, reboot and check

// setup wifi and save when connected
var Wifi = require('Wifi');
SSID='SSID';SSIDPASS='SSIDPASS';
 Wifi.connect(SSID, {password:SSIDPASS}, function(err){
   if (err === null){
     console.log('Connected to AP');
     console.log(Wifi.getIP());
     Wifi.stopAP();
     Wifi.save();
   }
 });

// reboot
require('ESP8266').reboot();
