Below are listed the most common issues that may arise when using P&S for the first time.
- Cannot Upload Program.
Please take a look on this checklist in order to see if you are missing any basic step.
Waspmote PRO checklist
It is for Waspmote, but is also valid for Plug&Sense!.
- My P&S is rebooting, What can I do?
Resets are usually due to a low battery level. Check the battery level,you can use the getting-battery-level example. We do not recommend working with battery levels under 20%-30%, without taking it into account in your code.
- How can I know which battery type has my P&S?
Waspmote Plug & Sense! includes a back sticker where it is shown battery type. Normally P&S units have a rechargeable 6600mAh battery, but other models are possible.
- How can I recharge my P&S?
You can charge the battery with USB or solar panel.
To charge the battery the ON/OFF button must be in ON position.
The battery could charge faster if you upload a code that does not waste energy, for instance the deep-sleep-mode example, but enlarging sleeping time as follows:
Original line: PWR.deepSleep("00:00:00:10",RTC_OFFSET,RTC_ALM1_MODE1,ALL_OFF);
Larger time: PWR.deepSleep("00:00:30:00",RTC_OFFSET,RTC_ALM1_MODE1,ALL_OFF);
New P&S: (since August 2014)
The ON / OFF button can be in ON or OFF position to charge the battery.
Obviously, non-rechargeable batteries cannot be recharged with any method.
- Recharging times.
A complete battery charge can last 24 hours using solar panel connector or 66 hours with USB cable. The solar panel connector can reach 280 mA of charging current, while USB can only reach 100 mA.
- How to reduce battery consumption of a waspmote P&S.
On P&S! devices, hibernate mode is not possible. However, you can use sleep and deepSleep modes. Besides that, try to turn on things only when your are going to use them and just after using then, turn them off.
- How can I check my P&S hardware?
You can use the factory default code to check your hardware: http://www.libelium.com/development/was ... test-code/
Take a look into the first printed lines on the serial monitor. They will say your radio protocol and some other relevant data.
- How to configure the Xbee inside a P&S
X-CTU tool from Digi can't be used in this case. You have to configure It by code, like in the Xbee_01_configure_Xbee_parameters example.
- My P&S nodes can't communicate to each other. what can I do?
- Check that the nodes have the same radio module.
- Check that both XBee have same networking parameters (PANID, CHANNEL, etc).
- Check destination MAC address.
- Check your node have the antenna connected.
- If you can not connect, you can use XBee example codes: Configure parameters, send packets and receive packets.
- External Solar Panel.
This panel should be connected to the external solar panel connector. Do not connect any sensor on this connector and also do not connect the solar panel to a sensor connector. You can damage internal circuitry.
If you are planning to use your own solar panel or power supply, maximum allowed voltage on the solar panel connector is 12V. A voltage between 6-7 V is optimal. We only recommend using official power sources.
If you want to use the solar panel connector to charge the battery in case of indoor installations, there is a special cable for it. Contact our sales department through filling next form

- ON/OFF button.
ON/OFF button includes a red ring LED, which can be managed by software. The usage of this LED will increase power consumption due to external LED consumes 4.4 mA.
By default, Waspmote Plug & Sense! comes with a code that blinks briefly (3 times in less than one second) this led when it is turned ON.
- Resetting Waspmote P&S.
It can be reset with an external magnet, with no contact, also using the Waspmote IDE. if you have your P&S connected by USB, you can reset it by closing and opening again the serial monitor.
- How to read data from SD files.
It is not possible to directly read the SD files as a pen drive. You should use a code to read the files and print its info by USB or send it via wireless. Use the sd-04-read-file example to read a file and the sd-06-list-files example To list all the files.
- More Questions about P&S.
We recommend to spend some time reading the documentation available in the development section:
