First of all, this is the stuff we are using on the robot:
Linksys WRT54G Router(Radio)
cRIO with the standard Modules(Analog, Digital w/ Sidecar)
Jaguars w/ CIMs(CAN), Sparks w/ Solenoid and Compressors(Although shouldn’t be relevant?)
Our team has used our T-Shirt canon(yes, it’s a bit old) for the past 2 years at homecoming at our school, but the communication with the radio has been weird. We have tried it many times with no people whatsoever in the stands and it works absolutely fine, but the 2 times that we used it with people in the stands(many hundreds of people) we get sparratic radio communications, although there is a solid green light in the DS, and there is anywhere from a 2-6 second delay for either using the joysticks or pressing the fire buttons. I was first thinking people cell phones were interfering with just noise, but someone told me that they wouldn’t put out anything on that frequency, I only saw one hotspot. Then I got thinking and thought devices might be auto-connecting to it but it has a password. I don’t know hardly anything about how WiFi works so I thought that the devices might be pinging the router but apparently it just broadcasts it out every so often. The only thing I can think of at this point is using a hidden network or switching to 5G, but as I said, I only saw 1 hotspot and I don’t know if changing the network to a hidden network would do any good. We had LOS and we were using 2.4G, not to mention we were only about 25 feet away. The problem did disappear when people started leaving the stands so I think that is a strong indicator of students’ cell phones interfering, but I don’t know why, and I don’t have any ideas on possible solutions. If anyone has any ideas of what it could be or have experienced an issue similar to that of ours, I would be grateful for any help you could provide. Thanks.
