mackrackit's ConnectOne example code

Up date..
Trying to set up the iChip using only AT commands like you are. Not having much luck. Have to get back to work. Will continue later.

Dave, I began to wonder if in my process of converting your ConnectOne example code to my 16F886 MCU and my parsing of the code into subroutines that I could call from my application might have done something that screwed up its ability to communicate with the iChip module. So I went back to your original example code which is a lot simpler and modified it slightly so it is supposedly compatible with 16F886, without parsing into subroutines. Below is the resulting code where I have annotated where it stops and won't execute any further. Still looks like I can't get communication with the iChip. Would appreciate you trying it to see if you can get it to communicate with your module.

I also tried using the AT+iFD command to reset the iChip to Factory Defaults, in hopes that it would connect.....I did this because of this quote in the iChip WiFi Configuration Manual which says " Assuming all WiFi related parameters are cleared to their default value, as is the case after a Factory-Defaults setting (AT+iFD), iChip will attempt to associate and connect to the closest available Access Point (AP) that does not have any security configured. " I used this statement to try to do this and it won't even compile as if there is a syntax error: SEROUT2 TX,6 [ "AT+iFD",$d ,$a ] 'Set iChip to Factory Defaults
I don't see anything wrong with this. Any ideas why this won't compile?

I used this statement to try to do this and it won't even compile as if there is a syntax error: SEROUT2 TX,6 [ "AT+iFD",$d ,$a ] 'Set iChip to Factory Defaults
I don't see anything wrong with this. Any ideas why this won't compile?

I at least figured out why this statement wouldn't compile....I forgot to put a comma after the SEROUT2 TX,6 . However, after fixing this and compiling/running it, the factory defaults didn't seem to happen.

I may have found part of the problem. I have placed a voltmeter on the pin that is RX going into the iWiFi and it stays at a constant 3.3 volts throughout this program...no fluctuations indicating any serial transmission. Also put it on the TX pin comming out of my MCU...also constant. This tells me that the serial interface from the MCU is not working. That would mean that the AT+iFD message never got to the module, hence no Factory Defaults. However, I don't know why or how to fix it. Any ideas?

[jellis00]

I changed all the SEROUT2 TX statements in the code to mode 396 to lower the baud rate to 2400 to see if this made the serial interface work. Still doesn't appear to work. BAFFLED!!
Is there any way to tell whether the asynchronous serial interface on a PIC chip that is using PortC.6 and PortC.7 is working?? I don't have an external serial interface to my PCB to use to see if it is working with a PC terminal or I would. I have the TX and RX pins hooked up only internally to the iChip module.

[mackrackit]

Post #32 has the link to the config utility. You will need a serial interface to your PC to use it along with a MAX232. A USB to serial adapter works fine.

A USB to serial adapter will also let you test you TX, also will help in debugging.

Hang in there, we will get this figured out.

Just received the below email for ConnectOne tech support confirming what you said about Config utility, so looks like the option is out for me since I don't have an external serial interface on my board.

From what I know now, my problem is really getting the PIC to establish serial communications on my board with my code to the iChip. Once that is done I should be able to use the http:// approach he mentions in the email to setup the iChip configuration. So if you ca help me figure out why the PIC isn't executing the serial interface, that will be the big step.

Here is their email:
Hi John,

According to our R&D, the LAN to WiFi Wizard is not operational and should not be used (it should have been removed from the s/w).

To configure the unit either use the FULL CONFIGURATION tool in the iChipConfig or manually type in AT+I commands using the “Dumb terminal”.
Once the unit is configured, it will save the parameters in non volatile memory.
You will need to power down the unit for the parameters to take effect.

Once you’ve setup the module for the AP you want to connect to and enabled the internal web server, you can than access directly the ichip web configuration page via http://x.x.x.x/ichip

All the information you need for setting up the module is available in the documentation I previously sent you.

Hello john and mackrackit..if it is ok to you..can i have ur schematic in full...tnx

[kenruizal]

john...what is best to be used it is with evaluation board or without evaluation board mini socket iwifi?
