LwM2M BG96 problem with connect leshan demo server

Hello, I am using a BG96 module with firmware BG96MAR02A07M1G connected to the NB-IoT network

I am trying to use lwm2m with leshan server, as the example in the lwm2m user guide.

My bootstrap.ini

{"bn":"/0/1/",
	"e":[
		{"n":"0","sv":"coap://leshan.eclipseprojects.io:5683"},
		{"n":"1","bv":false},
		{"n":"2","v":3},
		{"n":"10","v":102
		}]}

My lwm2m.cfg

{
APN=iie.iot;
RETRY_TIMEOUT=5;
RETRY_EXPONENT_VAL=2;
MAX_RETRY_TIMEOUT=120;
MAX_NO_RETRIES=5;
ACK_TIMEOUT=10;
REG_RETRY_TIMEOUT=5;
REG_RETRY_EXPONENT=2;
REG_RETRY_MAXTIMEOUT=480;
ROAMING_FEAT=0;
PER_REGSTATUS_FEAT=0;
BATTERY_LEVEL_THRESHOLD=20;
REBOOTSTRAP_REG_FAILS_MAX_NO_ATTEMPTS=2;
CARRIER_TYPE=0;
REG_EP_NAME=4;
BOOTSTRAP_EP_NAME=4;
}

My carrier_apn_cfg

APN_NAME=iie.iot
APN_CLASS=2
BS_IF_REG_FAILS=0
SHORT_SERVER_ID1=102
;

When I reboot de module I get this in the debug console:

Net: Net Registered
dss_netapp: DSS_NetApp Registered
atfwd_cli_app: Atfwd_Cli_App Registered
LWM2M_EXT: LWM2M_EXT Registered

LWM2M: State: STATE_REGISTER_REQUIREDLWM2M: 
LWM2M: State: STATE_REGISTERING

I never get the LwM2M: State: STATE_READY message, and of course my device does not appear in the server.

I thank you in advance for any help.
