TTN lorawan 923Mhz node 1: LMIC-arduino not working on 8266

This is made to test 1-CH gatewayV4(5) with 923-925Mhz https://things4u.github.io/
the exa,ple is taken from https://github.com/matthijskooijman/arduino-lmic
using the ttn-abp example:
first need to go to TTN, console and application to create an applicaiton:
1. you can name the applicaiton ID and description as you wish, but the applicaiton can only be low cast.
2.Also you have to select a application handler, choose the one near you, since the down link is related to to time windows

 

it would look like this



3. then register an device.
name the device ID, for the device EUI you can input one or click on the left block, then they will make one for you.

 after create, the device is in OTAA mode, go to setting , change it to ABP, then save.


when you back to the device overview, you will have info needed:
we need device address, network session key and appsession key


Now, goes back to the lmic ttn-abp example:
1. change the
static const PROGMEM u1_t NWKSKEY[16] =
static const u1_t PROGMEM APPSKEY[16] =
static const u4_t DEVADDR =
with the data from TTN pages
2. ping mapping, I'm using same connection as my 1ch gateway(8266+RFM95), so I make it as following. currently not using reset.
// Pin mapping
const lmic_pinmap lmic_pins = {
    .nss = 16,
    .rxtx = LMIC_UNUSED_PIN,
    .rst = 0,
    .dio = {15, 15, LMIC_UNUSED_PIN},
};

3. for the channel:line 204

I modified as this:
    LMIC_setupChannel(0, 923200000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(1, 923400000, DR_RANGE_MAP(DR_SF12, DR_SF7B), BAND_CENTI);      
    LMIC_setupChannel(2, 923600000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(3, 923800000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);    
    LMIC_setupChannel(4, 924000000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(5, 924200000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(6, 924400000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(7, 924600000, DR_RANGE_MAP(DR_SF12, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(8, 924500000, DR_RANGE_MAP(DR_SF7, DR_SF7),  BAND_CENTI);     
    LMIC_setupChannel(9, 868800000, DR_RANGE_MAP(DR_FSK,  DR_FSK),  BAND_MILLI);      
which match to my gateway frequency plan

and line 221, this is for downlink SF
    // TTN uses SF10 for its RX2 window in asia 2 frequ plan.
    LMIC.dn2Dr = DR_SF10;

it complied but I got failure from serial monitor:
Starting
FAILURE
D:\Dropbox\Arduino_projects\libraries\arduino-lmic\src\lmic\radio.c:689

 it seems to inside the radio_int(), may be I need to add an reset pin

after reading this:

https://github.com/matthijskooijman/arduino-lmic/issues/7

I change to this and try again:

// Pin mapping

const lmic_pinmap lmic_pins = {

    .nss = 16,

    .rxtx = LMIC_UNUSED_PIN,

    .rst = LMIC_UNUSED_PIN,

    .dio = {15, 15, LMIC_UNUSED_PIN},

};

the I comes to a watch dog reset

 ets Jan  8 2013,rst cause:4, boot mode:(1,6)

wdt reset

after checking google, it says this type of error due to unsupported lib fro 8266....

So, google again I got this:
