I have a few Cerbuino boards and RN-XV Wifly modules which share the XBEE interface.
I would like to use the GHI provided gadgeteer-driver of the RN171 module, for my RN-XV Wifly modules.
Is that an option, and if so, could somebody send me some information on that?
@ freeck - If you are still using Gadgeteer, then you will only need to modify the constructor of the driver to accept pin assignments and the COM string rather than a socket. If you are using pure NETMF then you will also need to convert the calls to the serial port and anything else Gadgeteer specific as well.
Thanks for the advise.
Question: the driver requires next to Rx and Tx, 2 extra signals i.e. RESET and RTS.
RESET is connected to the PB0-pin of the Cerbuino, but what about the RTS-signal?
According to the circuitdiagram of the Cerbuino the RESET seems to be disconnected from the CPU…!?
@ freeck - The reset pin is infact connected to the CPU at PB0 (pin 26). The RTS/CTS pins are not connected on the XBEE socket. These pins are only required for the driver if you are adding it to a K type socket. You may comment out the initialization of these pins in the driver and set the serial port constructor to not use handshaking.
Yes, I did so, and the driver is working now! So far so good, Great.
As my Wifly- module was not configured as an AP I tried to use the createAccessPoint method of the ghi-library, but that did not function properly. The wifly was visable as a AP, but I received no characters via the serial port from the browser. After a lot of frustrating experiments, I ran the in built program called web_app_238…Then an AP was created, and the webserver application is working now!
I do not understand the cause of this…but I can go forward from now…
Perhaps this is an known issue?
@ freeck So you were able to get the RN-XV Wifly working with the RN171 driver? Including AccessPoint mode? 8)
What changes did you make? Perhaps you would be able to post your updated driver to codeshare?
@ sandy -
Hi, I have same utilitiy and driver code for the GHI RN171 module. It works in AP mode and Join Network Mode. The code is not yet in a state that it can be posted here but if you want I can send it via E-Mail. However the driver has to be adapted to to the XBEE socket.
Send your E-Mail address if you are interested.
I changed a few lines of code, specific for theCerbuino board. Unfortunately I don’t have a source code control system …so a few extra modifications may be needed. BTW does anyone use a license free SCCS, with VS2012?)
int baud = 9600;
//int baud = 115200;
//_wifly = new GTI.Serial(socket, baud, GTI.Serial.SerialParity.None, GTI.Serial.SerialStopBits.One, 8, GTI.Serial.HardwareFlowControl.NotRequired, this);
_wifly = new SerialPort("COM1", baud, Parity.None, 8, StopBits.One);
_Port_Name = socket.SerialPortName;
_baud = baud;
//RTS = new GTI.DigitalOutput(socket, Socket.Pin.Six, false, this);
I did not continue testing the AP mode , but perhaps the source of Roland is useful…Be aware that the RV171 only supports 1 internet socket…
@ RoSchmi - Thanks, i will give your driver some testing
@ freeck - Looks good. I will give this a try when i receive my Cerbuino. Also, thanks for the info about support for a single internet socket.
