kandi X-RAY | ptm Summary
PTMD is a dynamic cabling verification tool to help eliminate cabling errors in networks. It takes a graphviz-DOT specified network cabling plan (something many operators already generate) and couples it with runtime information derived from LLDP to verify that the cabling matches the specification. The check is performed on every link transition on each node in the network. PTMD runs as a Linux daemon.

Answered 2021-May-18 at 06:08If you read the Visual Studio predefined macros documentation you can find compiler-specific macros which ben be used to identify if your code is being built by the Visual Studio C++ compiler.
For example the _MSC_VER
macro, which you can check for instead of _WIN32
.
As in:

Answered 2021-Apr-13 at 00:02Here's a stab at it. I can't debug it (since I don't feel like creating a database).
First I create a type to hold the results. You could just use a Tuple, but this seems clearer:

I am generating a table of entries in a MySQL database using PHP. Each record references a document. I am putting a button link in the table to download the document for that record. The documents largely link to csv files. However, when clicking on them, it loads the csv file in the browser, but I want to force it to download the file when the button is clicked.

Which seems to work - in chrome at least.

I would like to ask about how to save computational time about accessing List in nested loop. Here is an Rcpp example including two functions:
...ANSWER
Answered 2021-Apr-06 at 02:19You're doing an implicit conversion and a deep copy during every loop, so it's no surprise that the compiler can't optimize that away.
What you can do is pre-calculate all the etas and store them in a vector. (I filled in some work within the loop, since empty loops can be optimized out completely).

QUESTION
at first: I'm not a BLE expert so I try to describe my problem as good as I can and I apologize in advance if I don't use the right terms or definitions.
- I've bought a BLE-Energy-Harvesting button of type PTM 215B (1).
- I've installed node-red on Raspberry-Pi 2b (2)
- Locally on node-red the package node-red-contrib-generic-ble was install with npm (3)
when node-red is started I can see the elements of generic-ble-package and so I tried to configure the "Generic Ble In"-Item.
When I scan for devices, I have to push and release the button several times till it is shown in the list - that's no wonder because without these actions the button has no energy. But then it gets complicated. When I click on "Apply", the item tries to get the GATT(ributes) from the button.The problem is - as far as I understood - the button doesn't have any.
From the CLI I've used bluetoothctl to scan for devices and I've seen that the button is always recognized by the system (on-button-pressed and on-button-released).
I've also tried with different other node-red packaged but they had even more problems ( e.g. noble (4) could not be installed properly and it looks like abandoned )
I assume the problem is sitting in front of the screen but this is the second Saturday I'm trying to "install a button" and I really don't know how to proceed.
I've read (somewhere) that one of the strength of BLE is the possible usage of energy-harvesting -sensors. But does the "general-ble"-package do the job?
-If yes, how? -If no, which package should I use?
I'd really like to use a node-red-package because I want to expand an already existing flow.
I appreciate any help and/or link.
Thank you in advance.
Regards,
Mr P
Additional info:
- Raspbian: VERSION="10 (buster)"
- npm --version: 6.14.8

Answered 2020-Dec-21 at 23:10I found the way to do the job:
I installed the ble-beacon-scanner (1) and that works fine for my purpose.
As I understood: Beacons use ble-notifications, which don't share attributes and don't need a continuous connectivity.
The generic library unfortunately doesn't offer this part of the ble-protocol.
Thank you all.

Mr P
