Re: [dev] Hi, I have some question about Arduino(Wifi shield)

[Matta Jayaram]

Hi

 If we set the listening port number with 5 for Arduino MEGA(with
WiFi shield) or ESP8266. Whenever we do the DISCOVERY from IoTivity Client
or By Clicking Find Resource option in Eclipse Simulator It will Discover
the ESP8266 or Arduino MEGA (with WiFi shield) Device with port number
“4097” .

 Yes, all of us know that IoTivity Servers are Initially Multicasted to
224.0.1.187:5683 and Unicast (or listening) to device ip with some random
port number.

Once the Device Discovered with specific port number then IoTivity Client
Initiates GET,PUT,POST,..etc to that specific portnumber with Device IP.

 But here Arduino MEGA (with WiFi shield) or ESP8266 Device is
Discovered with port Number “4097”,IoTivity Client is Initiates
GET,PUT,POST,..etc
to that specific portnumber with Device IP (DeviceIP:4097) but the device
listening port is 5.

we need to change code on client side ,like when ever it discovers
devices with port number 4097 skip that 4097 port number and sending it to
the other port Number(5 or any other server side listening port number).

  In the SDK used by the ESP8266/Arduino port, the underlying LWIP
library implements a function tcp_new_port as part of the tcp_client
library portion of the LWIP library.

This library is provided as a binary library by Espressif rather than as
open source.Currently that function works by sequential port allocation
starting from a fixed value that is

reset on every reset. Thus, the first tcp_connect() call from every reboot
will always use source port 4096, the second will use 4097, etc.

  This is a problem still exist for both Arduino MEGA(with WiFi shield)
& ESP8266 .I think changing the code on client side for specific port
number is not good and also try with Ethernet Cable.

[dev] Should IoTivity Arduino support be dropped?

[Matta Jayaram]

Dear Team,
Should IoTivity Arduino support be dropped?

Before answering above question ,

1.we know that arduino Wifi / Ethernet shield will not support multicast.

2.Even if we use unicast also we are unable to create multiple resouces
with it (1.a/fan,2.a/light...etc)

3.Unable to process payload more than 255 bytes

4.When IoTivity client is Performing Discovery its destination address is
always 4097.

if you Drop the Arduino Boards Support No problem, But if you
Drop the Arduino SDK support then as per my understanding we are unable to
Build IoTivity for Arduino SDK Supported Boards like ESP8266,nrf5XXetc
Modules.

   If you provide Arduino SDK Support  on IoTivity - Constrained
side then it's ok

[dev] IoTivity Resource collection Observe

[Matta Jayaram]

Dear Team,

  Now I am working on resource collection ,created 6 resources and I am
able to perform GET,PUT,POST on it individually & all at a time.

  Now I am trying to Implement observe method,But OIC specification
does not say anything about collection resources should not support
observer functionality.Its very common that server can have collection type
resources and client can observe its status.

 Should I need to take care of Application entityHandler for handling
the observe requests on collection resource ?

Please suggest me

Dear Thiago,

   In My previous Email I shared Memory Footprints for IoTivity and the
OS { IoTivity-Constrained + OS (RIOT / Contiki Supported Boards)}.Without
Enabling Security I generated above .hex /.elf files.

[dev] Iotivity with ESP8266

[Matta Jayaram]

Hi,

 Now I am Trying to create Multiple Resources with ESP8266 ( adding two
resources for same ESP8266 Device )

 From Eclipse Simulator I am unable to Discover these Resources and I
am getting 272 bytes of payload ,But for a Single Resource I am getting 209
bytes of payload & I am able to Discover it.

If I decrease the Payload size then I am able to Discover the Multiple
Resources.

I found this same issue is exists in previous version 1.1.0. and it fixed
in 1.1.1 version for Memory Constrained Devices like Arduino,ESP8266.

Case 1:I am able Discover multiple Resources by Decreasing the Payloadsize
(this is not a right way because I am unable to create resources with all
neccessary things&options )

Case 2: Even I tried to increasing the size of it before return
cborEncoderResult still I am unable to Discover Multiple resources from
Eclipse Simulator.

And one more thing that in Iotivity code I found these lines and I changed
it to other higher values

/* 320 is maximum size of a CoAP PDU for embedded
platforms...Arduino,ESP8266,...etc*/

/* 1400 is maximum size of a CoAP PDU for big platforms*/

then also I am unable to Discover Multiple Resources.

Please Suggest on it.

[dev] Iotivity with ESP8266

[Matta Jayaram]

Dear Team ,

 Now I am Trying to create Multiple Resources with ESP8266 and I am
following Link referred & Provided by the Khaled Qorany and Khaled Elsayed.

While Creating Multiple Resources like light,fan,..etc .

>From Eclipse Simulator I am unable to Discover these Resources and I am
getting 272 bytes of payload ,But for a Single Resource I am getting 209
bytes of payload & I am able to Discover it.

File:/resource/csdk/security/src/pstatresource.c

Line Nums : 38 to 43

/** Default cbor payload size. This value is increased in case of
CborErrorOutOfMemory.

* The value of payload size is increased until reaching below max cbor
size. */

static const uint16_t CBOR_SIZE = 512;//***I changed it to 1024 & 2200
&4400***//

// Max cbor size payload.

static const uint16_t CBOR_MAX_SIZE = 4400;

Even still I am unable to Discover Multiple Resources when I clicking
FindResource option on Eclipse Simulator.

Please Suggest on it.

[dev] Questions about ESP8266 porting

[Matta Jayaram]

Hi,

 All of us Know that Espressif ESP8266 Modules Supports Different
SDK's(RTOS,NON-OS).But for
porting Iotivity to ESP8266 I used Arduino<https://github.com/esp8266/Arduino/>,
so almost all the code written for Arduino can be easily reused with
ESP8266.(for more info you can you can check Mailinglists of Khaled,Damian
Rakowski)

  here are ESP8266 parameters. Please note there are various variants, so I
chosen one of the most common options (ESP8266-12E)

CPUSpeed  80MHz(It can also reach a maximum value of 160MHz)

Flash Memory size--512kB

There is no programmable ROM in the SoC, therefore, user program must be
stored in an external SPI flash.

This module is mounted with an 4 MB external SPI flash to store user
programs.

Suggested SPI Flash memory capacity:

?OTA is disabled:minimum flash memory that can be supported is 512 kB

?OTA is enabled: minimum flash memory that can be supported is 1 MB

a SPI flash with larger memory size is preferred. Theoretically speaking,
upto 16 MB memory capacity can be supported.

Several SPI modes can be supported, including Standard SPI, Dual SPI, and
Quad SPI.Therefore, please choose the correct SPI mode when you are
downloading into the flash, otherwise firmwares/programs that you
downloaded may not work in the right way.

Dimensions16mm * 24mm * 3mm(Length
x Width x Height)

Priceabout -$3

*ESP-12E Features: *

?802.11 b/g/n

?Integrated low power 32-bit MCU

?Integrated 10-bit ADC

?Integrated TCP/IP protocol stack

?Integrated TR switch, balun, LNA, power amplifier and matching network

?Integrated PLL, regulators, and power management units

?Supports antenna diversity

?Wi-Fi 2.4 GHz, support WPA/WPA2

?Support STA/AP/STA+AP operation modes

?Support Smart Link Function for both Android and iOS devices

?Support Smart Link Function for both Android and iOS devices

?SDIO 2.0, (H) SPI, UART, I2C, I2S, IRDA, PWM, GPIO

?STBC, 1x1 MIMO, 2x1 MIMO

?A-MPDU & A-MSDU aggregation and 0.4s guard interval

.Deep sleep power <10uA, Power down leakage current < 5uA

?Wake up and transmit packets in < 2ms

?Standby power consumption of < 1.0mW (DTIM3)

?+20dBm output power in 802.11b mode

?Operating temperature range -40C ~ 125C

[dev] Iotivity With ESP8266

[Matta Jayaram]

Dear Team,

I ported Iotivity to ESP8266 & I am able to control it From
Iotivity Ported Ubuntu PC. Now I want to control it from Iotivity based
Android App.That App has to Work Similar to Generic Eclipse Simulator
Iotivity Client Plugin to Initiate GET,PUT with Different Payloads, POST,
OBSERVE Queries. If any of you find Sample Iotivity Android Client App or
Web Interface please suggest it .

[Matta Jayaram]

Dear Vishnu,

Before Porting Iotivity to ESP8266 analyze the steps to Port
iotivity to Arduino .Problem with Wifi shield.use that OCServer program as
reference and identify why this(mentioned in iotivity 1.1.1) wifi shield
not supporting Multicasting.

[dev] ESP 8266 Support in IoTivity

[Matta Jayaram]

Dear Vishnu,

 Yes it is possible , I ported Iotivity to ESP8266 and I builted an
Smartplug prototype with it.

For reference you can use that sample programs available for arduino with
few changes.

[dev] Iotivity with Arduino and ESP8266

[Matta Jayaram]

Dear Developers,

 Any of you tried Below Combination

CASE1:Controlling Iotivity ported Arduino+ethernet shield (server) from
Iotivity ported Ubuntu PC(Client){Terminal/Eclipse Simulator}

CASE2:Controlling Iotivity ported ESP8266(server) from Iotivity ported
Ubuntu PC(Client)


Ubuntu PC(Client) Log (ESP8266 used as Server)

45:15.156 DEBUG: OIC_CA_RETRANS: wait..(100)microseconds

45:15.156 INFO: OIC_CA_IP_SERVER: unicast ipv4 sendTo is successful: 26

as I Know that Arduino & ESP8266 Device will Support IPV4 only,Please
correct me if I am wrong

(iotivity/resource/csdk/connectivity/src/ip_adapter/arduino/caipserver_wifi.cpp

iotivity/resource/csdk/connectivity/src/ip_adapter/esp8266/caipserver_wifi.cpp)

 From the Ubuntu Client I am able to Send unicast ipv4 Message but from
ESP server Device I am not getting any Response

Please Suggest on it

[dev] Iotivity with Esp8266

[Matta Jayaram]

Dear Developers,

Ported Iotivity to ESP8266 Device.Now I am Trying To Control Esp8266
(Server) Device.

*CASE1:*Using one Esp8266 Device as Client and Another Esp8266 Device as
Server   *Device Discovery,GET,PUT...etc are Working **fine.*

*CASE2:*Now I am Trying To Control Esp8266 (Server) Device by Running the
occlient/simple client on Iotivity Ported Ubuntu PC.

  Here the Strict rule is that I am Not allowed to change anything on
ClientSide .cpp file (Ubuntu PC).

To achieve it I made some Changes in ocserver.cpp (Esp8266 server)file.

*Device Discovery is Working ,When I issueing the GET Request from Eclipse
Simulator or ./occlient -t 9 From Ubuntu terminal My ESP8266(Server) not
Responding to it and I am also verified even it is not entering into
the(**OCEntityHandlerCb
function)*

OCEntityHandlerResult OCEntityHandlerCb(OCEntityHandlerFlag flag,
OCEntityHandlerRequest * entityHandlerRequest, void */*callbackParam*/)

*{*

// This is the entity handler for the registered resource.

// This is invoked by OCStack whenever it recevies a request for this
resource.

*}*

Please Suggest on it,

[dev] Iotivity with ESP8266

[Matta Jayaram]

Dear Developers,

 I have Ported Iotivity to the ESP8266. I have also gone through
Aurdino sample programs and wrote simple server program for ESP8266.

For this Discovery method is working properly  but facing issues with
GET,PUT,etc.. methods as getting OC_STACK_COMM_ERROR.

If any of you working on this, please suggest.
