Any support or help will be great. (3 Replies)

My favorite projects are always related to the "latest" tech in command and control, networking and network communications. This Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield seems to be the "latest and the greatest" as far as 3G and GPS, as far as I can see so far, but I has it drawbacks for sure.... (6 Replies)
Today I received my NB-IoT Arduino Shield for AIS (Thailand). Here is a "pinout" photo of the shield.
My shield looks just like the one above, for the most part. I'll post another photo of the actual device later.
When I received the shield in the mail, I went immediately to a local... (8 Replies)
Normally I have very good experiences buying from AliExpress, but in this case with Elecrow, I'm disappointed.
After confirming with Elecrow on AliExpress that their Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield for Arduino would work with 3G SIM cards in Thailand, I purchased one. My plan was to... (1 Reply)
Here is a sketch to do basic testing for the Arduino UNO and the MLT-BT04.
This BLE module works with IOS (iPhone) and I'll add some details on my IOS testing with an iPhone in a follow-up post.
For now, here is the basic BLE (HM-10) sketch for the Arduino UNO:

With a little bit of work, was able to build a nice "Wuhan Coronavirus Status" app using MQTT and the IoT-OnOff app. More on this technique here:

The result turned out nice, I think. I like the look and... (10 Replies)
Normally I'm not into kits, but I thought my wife would enjoy this one since she is a big fan of robots and droids on StarWars!
We are done with the basic mechanical assembly and starting on the electronics assembly today.

attach
ATTACH(5) File Formats Manual ATTACH(5)NAME
attach, session, nop - messages to initiate activity
SYNOPSIS
Tnop tag[2]
Rnop tag[2]
Tsession tag[2] chal[8]
Rsession tag[2] chal[8] authid[28] authdom[48]
Tattach tag[2] fid[2] uid[28] aname[28] ticket[72] auth[13]
Rattach tag[2] fid[2] qid[8] rauth[13]
DESCRIPTION
The nop request does nothing overt but may be used to synchronize the channel between two service hosts initially.
The session request is used to initialize a connection between a client and a server. All outstanding I/O on the connection is aborted.
The set of messages between session requests is called a session. The host's user name (authid) and its authentication domain (authdom)
identify the key to be used when authenticating to this host. The exchanged challenges (chal) are used in the authentication algorithm.
If authid is a null string no authentication is performed in this session.
The tag should be NOTAG (value 0xFFFF) for a nop or session message.
The attach message serves as a fresh introduction from a user on the client machine to a server. The message identifies the user (uid) and
may select the file tree to access (aname). The ticket and auth arguments contains authorization data derived from the exchanged chal-
lenges of the session message; see auth(6).
As a result of the attach transaction, the client will have a connection to the root directory of the desired file tree, represented by
fid. An error is returned if fid is already in use. The server's idea of the root of the file tree is represented by the returned qid.
ENTRY POINTS
An attach transaction will be generated for kernel devices (see intro(3)) when a system call evaluates a file name beginning with Pipe(2)
generates an attach on the kernel device pipe(3). The mount system call (see bind(2)) generates an attach messages to the remote file
server. When the kernel boots, an attach is made to the root device, root(3), and then an attach is made to the requested file server
machine.
