Dear Forum,
Hope you are all doing well.
I have been working with different kind of microcontroller based systems , recently i am working on a machine like POS and need its data directly to my server. I have been reading about wifly and decided to purchase (maybe my wrong selection) … last day i received my Wifly Shield RN-131C.
As per all your help , ideas, i started to work over it but i could not understand how to setup it. Because i want to setup with my microcontroller AVR not with Ardiuno and i dont have it.
I have few questions below i hope you would answer it :
-
on WiFly Shield RN-131c, there is Vin, Gnd, +5V , +3.3V and RESET … Where i should give the power supply. I checked in the datasheet / manual there is regulator installed between RN-131C chip and VIN so i have connected 3.3V to Vin and GND … Wifly Shield was turned ON. is there OK?
-
After connect my module with 3.3V supply there is no voltage on TX pin . Normally there should be voltage in my case 3.3V ?
-
I tried to connect the module with Serial cable using MAX232 TTL level converter using voltage divider to RX pin 3.3V to avoid damage the pin and connected to my PC COM1: and applied escape sequence $$$ but nothing happened.
-
I checked the module WiFly came with 2.38 Firmware. i setup it with adHoc network and put in this mode with PIO9 pin to high 3.3V and i came in to adhoc mode and connected through TeraTerm to 169.254.1.1:2000 and setup : ssid, phrase , join = 1 and restarted the module it connected to my Router and i can give PING … but still could not connected through serial TX RX because i wanted to use with microcontroller to send data to the server.
-
On one post i read to setup i should update the firmware so i did with FTP U and it was connected and updated to firmware 4.00
after that now i read there is no adhoc network and replaced with APMODE … i tried to setup again the same … but still not connected to my serial cable to PC … but now when i give SCAN command it crashed and nothing come out … :(( … and disconnect …
I am totally fadeup what kind of is this module … is there any technical support from any end ? Have you ever faced this type of problem. …
Please reply me so i can do further or suggest me what i should do .
Now when i turn on the module … with Set wlan join 1 … then it connect to the server and GREEN LED blink slow . means IP Address OK but i can not see IP on my router …
Best regards,
Shan
