I am using this library https://pub.dev/packages/flutter_reactive_ble for scanning the beacon. and for broadcasting a beacon I am using an android app called beacon simulator and it has got beacon UUID, majorID and minorID for each hosted beacon.
here the UUID is '0546b93b-f113-438d-8bab-b9e766dd'
but while scanning I am unable to look out for UUID instead I am getting this response in this structure.
DiscoveredDevice(id: 14:49:2F:BB:D5:97, name: , serviceData: {}, serviceUuids: [], manufacturerData: [76, 0, 2, 21, 5, 70, 185, 59, 241, 19, 67, 141, 139, 171, 185, 231, 102, 208, 17, 119, 0, 0, 0, 0, 191], rssi: -39)
Is there any way I can get the beacon's UUID in the format '0546b93b-f113-438d-8ba...'
Or any better way to uniquely identify a device? I know we can search for the device's Bluetooth address, but that just keeps on changing.
Thanks in advance.
New to software development, I'm working through Big Nerd Ranch's book 'Swift Programming'. One of the challenges set by the book is to print an array within a dictionary that contains 15 zip codes and to have them split across three lines in groups of five. The formatting must exactly match how it appears in the book.
I have tried to solve the issue using the information taught in the book with assistance from the developer documentation.
No dice.
This is what I need to print:
Caterham has the following zip codes: [111, 111, 111, 111, 111,
222, 222, 222, 222, 222,
333, 333, 333, 333, 333]
However this is the closest I can get...
var areaCodes = ["Caterham": [111, 111, 111, 111, 111], "Coulsdon": [222, 222, 222, 222, 222], "Purley": [333, 333, 333, 333, 333]]
var caterhamCodes : [Int] = []
for (_, values) in areaCodes {
caterhamCodes += values
}
print("Caterham has the following codes: \(caterhamCodes[0...4]),")
print(" \(caterhamCodes[5...9]),")
print(" \(caterhamCodes[10...14]).")
which prints:
Caterham has the following postcodes: [111, 111, 111, 111, 111],
[222, 222, 222, 222, 222],
[333, 333, 333, 333, 333].
Essentially, I need what I have above minus some square brackets and without the punctuation after each time a block of zip codes is printed. The book specifies that I might need to use a parameter called terminator. It also mentions I might need to learn how to represent special characters in string literals.
I appreciate that this is probably a high level question with a simple answer, but I'm only a few weeks into learning, so I hope I can be forgiven for asking at least a few silly questions!
Welcome to the developer community and have a nice stay!
I am trying to put answer as simple as possible, so here is my attempt:
var areaCodes = ["Caterham": [111, 111, 111, 111, 111],
"Coulsdon": [222, 222, 222, 222, 222],
"Purley": [333, 333, 333, 333, 333]]
let codesArray = areaCodes.values.sorted(by: { $0[0] < $1[0] })
let caterhamString = "Caterham has the following zip codes: ["
var printString = caterhamString
for (index, area) in codesArray.enumerated() {
for code in area {
printString += "\(code), "
}
if index != codesArray.count - 1 {
printString += "\n" + String(repeating: " ", count: caterhamString.count)
}
}
print(printString.dropLast(2).appending("]"))
Hope this helps! Good luck!
Here is a way of getting the desired output :
let intro = "Caterham has the following zip codes: ["
let spaces = ",\n" + String(repeating: " ", count: intro.count)
let areaCodes = ["Caterham": [111, 111, 111, 111, 111], "Coulsdon": [222, 222, 222, 222, 222], "Purley": [333, 333, 333, 333, 333]]
let codes = areaCodes.values.sorted { $0[0] < $1[0] }
var output = intro +
codes.map { $0.map{ String($0) }.joined(separator: ", ") }
.joined(separator: spaces)
+ "]"
print(output)
Which prints
Caterham has the following zip codes: [111, 111, 111, 111, 111,
222, 222, 222, 222, 222,
333, 333, 333, 333, 333]
I wanna send email when spider closed, code is like this:
def close(spider, reason):
# mailer = MailSender.from_settings(self.settings)
from scrapy.mail import MailSender
mailer = MailSender(

mailfrom="rhys***#163.com",
smtpuser="rhys***g#163.com",
smtppass="***",
smtpport=25
)
body = u"""
content
"""
subject = u'title'
mailer.send(to=["rhys***#qq.com"],
subject=subject.encode("utf-8"),
body=body.encode("utf-8"),
cc=['12202012**#qq.com'])
But I got an error like this:

anybody can explain why?
I use python2.7 and scapy1.4. if I comment the code mentioned above everything is just ok
thanks
I bumped to twisted 17.9 and the problem went away.
I'm trying to include a typoscript on the child pages of the page it's included on.
On page id 272 I have included in the setup a typoscript file:
<INCLUDE_TYPOSCRIPT: source="FILE:fileadmin/templates/typoscript/fancyBoxPopup.ts">
And I only want this typoscript to run on that pages children.
So I tried this:
[globalVar = TSFE:id != 252, 253, 254, 270, 272, 271, 273, 274]
But that makes the script run on all children and parents (those listed in the statement)
Here is the full script:
[globalVar = TSFE:id != 252, 253, 254, 270, 272, 271, 273, 274]
page.includeJS >
page.includeJS.ieFixes = fileadmin/templates/js/ieFixes.js
columnWidth {
page {
main = 400
}
}
[end]
I think I manage to fix it.
I found PIDupinRootline.
So the final code looks like this:
[PIDupinRootline = 252,253,254,270,272,271,273,274]
...
[end]

but getting the following error while parsing
Error Domain=NSXMLParserErrorDomain Code=39 "The operation couldn’t be completed. (NSXMLParserErrorDomain error 39.)"
I read the documentation and also varify the syntax of XML, but didn't find what issue is with it.
Can anyone give any idea or help?
check these error code in apple documentation
