Error Code
Description
-92 (0xA4)
DNS response timed out
-95 (0xA1)
Unable to send data as ARP is not resolved
-100 (0x9C)
DHCP handshake failure
-113 (0x8F)
Unable to send data because of connectivity
disruption (such as AP switched off abruptly)
-121 (0x87)
Error issued when trying to connect to a non-
existent TCP server socket
-124 (0x84)
Connection establishment failure.
-127 (0x81)
Socket already exists.
-128 (0x80)
Attempt to open more than 8 sockets
-131 (0x7D)
DHCP_MODE parameter in “Set IP Parameters”
command is set to a value other than 0 or 1.
-211(0x2D)
This code is returned in the following scenario: An
LTCP socket is opened in the module. The remote
peer tries to connect to the socket using a client
socket, by sending a SYN packet (according to
TCP protocol). The module in turn responds with a
SYN+ACK packet. The remote peer is now
supposed to send an ACK packet. If this packet is
missed or does not reach the module, the module
retries sending the SYN+ACK packet 4 times, and
if the maximum number of retries does not lead to
reception of an ACK from the remote terminal, the
module returns this error to the Host and closes
the LTCP socket.
1 (0x01)
Wireless configuration failure
25(0x19)
Invalid value supplied as input in
at+rsi_authmode command
51 (0x33)
Keep alive timeout. On lack of activity over an
existing TCP socket connection, the module sends
out a Keep alive frame to the remote terminal. If
there is no response, the module closes its TCP
socket and sends out an asynchronous message
ERROR<Error_code=0x33>
64 (0x40)
Tx buffers are not available. The Host should stop
sending data to the module for some tens of
millisecs to relax the buffers
65 (0x41)
A packet of size more than 1460 bytes (TCP) or
more than 1472 bytes (UDP) is sent in at+rsi_snd
command.
66(0x42)
Zero TCP/UDP payload is sent from the module.
