Sigfox – WiSOL SFM10R1 – SNOC Board

WiSOL SFM10R1: a cheap Sigfox Module made by WiSOL available as devkit from SNOC/Yadom.

The only strange thing with this WiSOL module is that it responds with “ERROR: parse error” at the usual “AT” command.

A simple test code that sends some data to the network respecting the constraints:

[sourcecode language=”C”]

/*
Sigfox Module Test Unit
*/

int button = 2;
int led = 13;

void setup() {
// WiSOL works on 9600:
Serial.begin(9600);
// some basic LED debug info
pinMode(button, INPUT);
pinMode(led, OUTPUT);
// more to go for the receive function
// add ",1" for the downlink frame
}

void loop() {
int buttonState = digitalRead(button);
if (buttonState == LOW){
Serial.println("AT$SF=000011110000");
// some basic LED debug info
digitalWrite(led, HIGH);
delay(800);
digitalWrite(led, LOW);
delay(200);
digitalWrite(led, HIGH);
delay(800);
digitalWrite(led, LOW);
delay(200);
// obey to the max 1 msg every 10 min rule
delay(600000);
}
else {
// basic LED debug info
digitalWrite(led, HIGH);
delay(50);
digitalWrite(led, LOW);
delay(1000);
digitalWrite(led, HIGH);
delay(50);
digitalWrite(led, LOW);
delay(1000);
digitalWrite(led, HIGH);
delay(50);
digitalWrite(led, LOW);
delay(1000);
digitalWrite(led, HIGH);

The EFM32 Development Kit – Gecko, G890F128

EFM32 Development Kit

The EFM32 Development Kit features the EFM32G890F128 MCU (128 kB flash + 16 kB RAM) and is one of the best kits designed for low power device development.

The Advanced Energy Monitoring (AEM) system is practically a very good power monitor and logger, embedded in the Development Kit. Some other kits are doing this in the IDE, but to have it with a display onboard is awesome.

A large spectrum of techniques, from using different low power modes to switch-off peripherals can be tested directly and all with one kit.

The on-board Segger J-Link enables debugging.

The OOB configuration enables that the EFM32 can be programmed with many demo programs selected with the 320×240 TFT Display GUI and the power consumption can be monitored on the same TFT after programming.

Some features:

  • Single ended and differential ADC inputs on BNC connectors
  • Line-in and Line-out stereo audio amplifier with 3.5 jacks
  • IrDA, RS232
  • MicroSD card reader
  • 4MB 70ns PSRAM+ 16MB 90ns NOR Flash + 2Kb I2C EEPROM
  • Accelerometer and LDR

javapath javaw unspecified error

Few words about this annoying error:

javapath javaw unspecified error The cause is the C:\ProgramData\Oracle\Java\javapath symlink system that isn’t fully working.

The quick solution is to add the full path to your own jre’s bin folder (Ex.: C:\Program Files (x86)\Java\jre1.x.y_z\bin) to the PATH (Windows System Variable).

Testing that is all ok can be made also by running “java -version”.

If other java bin is missing it can be restored from the no-extension zip file from C:\ProgramData\Oracle\Java\installcache .

Anaren LR09A

Anaren LR09A

The LR09A (A110LR09A) is a module built by Anaren Inc based on the sub-1 GHz RF transceiver – CC110L.

For evaluation is really easy to use the AIR Boosterpack

TI Link: http://www.ti.com/tool/430boost-cc110l

Anaren Link: https://www.anaren.com/air/cc110l-air-module-boosterpack-embedded-antenna-module-anaren

Using one pcb for stand-alone operation:

On the PCB there are some DNP components that are needed only for the stand-alone configuration.

  • one simple S1 push switch is used for pairing
  • two 47k pull-up resistors – one 0603 as R1 and one at P1.3 (I don’t know why I can’t see the footprint)
  • one 0603 LED as D1 and his 0603 limiting resistor R2
  • some 0.1uF decoupling caps

The MSP430G2553 needs to be programmed with the Anaren Firmware and configured with ATC – BoosterStack Lite as Sensor (Application State Selector).

TI CC3200 Launchpad – Quick Guide

TI-Exosite_CC3200A quick start guide to the CC3200 Launchpad:

Out Of the Box feeling

OOB application is very nice, you can connect to the AP without security and then you go to the 192.168.1.1 (or http://mysimplelink.net , as indicated by TI, if you think that’s shorter…). Here answers a small webserver that serves some (uncompressed) html files that  are a frontend to the configuration settings and also some nice demo programs and documentation.

More

Prerequisites:

Uniflash Simplelink: The flashing tool for the CC3200 http://www.ti.com/tool/uniflash

Jumper on SOP pins.

Uniflash wiki UG: http://processors.wiki.ti.com/index.php/CC31xx_%26_CC32xx_UniFlash

The CC3200 SDK + Service pack can be downloaded from here: http://www.ti.com/tool/cc3200sdk

Some IoT provider, I chose Exosite. Step by step account and usage documentation: https://support.exosite.com/hc/en-us/articles/202271424–CC3200-Wi-Fi-Launchpad

Shortlist:

Create a TI Exosite account https://ti.exosite.com

Add the device mac to the Exosite Dashboard

Flash the Exosite firmware on the CC3200 Launchpad

Enjoy!

Issues:
  • Profiles won’t be saved if the WPA2 key is too long. Even in OOB Fw.
  • Flashing without format won’t work.
  • Formatting various sizes (1MB, 2MB, 4MB, 8MB, 16MB  from Format Options window that comes after you push Format button) leads to strange results, my CC3200 Launchpad has responded well only on 4MB. Even the OOB was unable to restore the board without reformatting to 4MB.
  • I noticed that sometimes the CC3200LP communication enters in a strange mode, appearing offline to Exosite and the Dashboard is showing up some negative temperatures. The LP responds to ping, the uptime displayed by the http server is ok. Only a power cycle reset solves it…
Fastest way:
  1. Select COM port, put jumper on SOP pins, verify using Get Version (Reset push-button required).
  2. Formatted 4MB, nothing else checked.
  3. Apllied Service Pack Update.
  4. Flash the desired firmware.
  5. Remove SOP jumper. Put on the AP Jumper (VCC-P58)
  6. Connect to the AP without security
  7. Create a Profile with the local WiFi configuration (SSID, Key) and give it a index number. Save.
  8. Reset the board and wait the boot and connect sequence.
If you try to restore the OOB firmware, you get the original status by opening with Uniflash the out_of_box.ucf that comes in the CC3200SDK\cc3200-sdk\example\out_of_box\html folder.

The public dashboard hosted on Exosite: https://ti.exosite.com/views/3194349686/3199082241

 

Late edit:
  1. The problem was due to a high current thing, and brings the CC+Exosite FW  in the same boat with the Fluke 233  rev.1 @36mA in active mode…
  2. Preproduction Silicon doesn’t support SDK > 1.1
  3. Exosite’s guide for those who want to switch from Portals to Murano https://community.exosite.com/t/how-to-use-murano-in-my-own-cc3200-board/316/2
Even later:
  1. Connection issues are mainly because of the SOP (Sense On Power) Jumpers. Flashing/Programming can be done with 100 configuration, that means only one jumper, placed on position labeled 2.
  2. Using the programmed configuration will be done removing that SOP jumper
  3. Uniflash 4.0 can’t be used for CC3200, use instead the old 3.4.x version
  4. The COM Port speed setting: 921600

Upverter Schematic Capture + PCB Layout – online

upverter

Just looking for PCB Suites prices, I found the upverter. It seems a very good way if you like to pay a monthly subscription price or you agree to share all your work…

The export function has a wide palette: Gerber RS-274X, Json, NC Drill – Excellon, Pick and Place CSV and Tempo format, PNG, 3D STL, CSV Netlist, CSV BOM.

The library claims to be very rich, but the parts that I was searching for wheren’t available. Maybe you should  build your own components and share, so after some months will be more complete.
