TWELITE APPS

What is Interactive Mode

Interactive mode is the mode to perform detailed settings of TWELITE APPS.

You can make necessary settings when you want to communicate with multiple groups or reduce communication errors.

Connection with PC

For TWELITE	For MONOSTICK
Attach the TWELITE R series to the 7P interface prepared on the parent board and connect to the PC using a USB cable.	Connect the MONOSTICK to the PC’s USB port. TWELITE R series is not required.

For TWELITE DIP (BLUE/RED)	For Others
Attach to TWELITE R series and connect to the PC using a USB cable.	For TWELITE series with 7P interface, attach TWELITE R series and connect to the PC using a USB cable.

Switching to Interactive Mode

When Using TWELITE STAGE

TWELITE STAGE APP is an integrated development tool that includes firmware writing and configuration of TWELITE, as well as a function to display received data.

1. Launch TWELITE STAGE APP

2. Select “Interactive Mode” from the menu of TWELITE STAGE APP

When Using Terminal Software

You can also use general terminal software.

1. Launch terminal software on the PC (communication settings: 115200bps/8-N-1)
2. Reset TWELITE.
3. Slowly press the + key on the PC keyboard three times (interval 0.2 to 1 second). If it does not work well, keep entering + repeatedly.

To exit interactive mode, press + three times again.

Operation of Interactive Mode

Interactive mode displays a screen like the following.

--- CONFIG/TWELITE APP V1-00-2/SID=0x81000038/LID=0x78 ---
 a: set Application ID (0x67720102)
 i: set Device ID (--)
 c: set Channels (18)
 t: set mode4 sleep dur (1000ms)
 y: set mode7 sleep dur (10s)
 f: set mode3 fps (32)
---
 S: save Configuration
 R: reset to Defaults

The displayed content varies depending on the firmware type and version.

Steps

1. Select value: press the first letter alphabet
2. Specify value: input the value
3. Confirm value: press Enter
4. Save value: press S (uppercase)
5. Apply value: restart TWELITE

Values in parentheses indicate the current setting.

Pressing R (uppercase) resets to default values (apply with S).

Example of Operation

To set the Application ID to 0xBEEFCAFE, input as follows:

Input Application ID (HEX:32bit): BEEFCAFE

Common Settings for TWELITE APPS

Frequency channel, application ID, device ID, retry count, and transmission output settings are common to TWELITE APPS.

Application ID and Frequency Channel

Devices must have the same application ID and frequency channel to communicate.

a: Application ID

Setting the same value to all devices communicating allows logical network separation.

TWELITE discards packets received from devices with different application IDs. Therefore, multiple groups can be established within the same frequency channel.

c: Frequency Channel

Setting the same value to all devices communicating allows physical network separation.

TWELITE conforms to the IEEE802.15.4 standard and divides the 2.4GHz band into 16 channels.

To change the frequency channel, press c (lowercase).

Use of Channel Agility (usually not recommended)

By specifying multiple channels separated by commas, channel agility can be enabled.

Channel agility improves communication success rate in poor communication environments by switching multiple frequency channels at regular intervals during communication.

Up to 3 channels can be specified simultaneously. The specified channels are switched in order at regular intervals for transmission. The receiver also switches channels in order at regular intervals for reception.

Reception is not possible during channel switching. In normal communication environments, reliability is lower than specifying a single channel. Since the number of transmissions from the child device needs to be increased, it is a wasteful method in terms of battery consumption. However, use it when you want to handle situations where certain channels become completely unusable. Normally, it is recommended to specify a single channel after identifying a channel with less interference in advance.

Default Values for Each TWELITE APP

i: Logical Device ID

The logical device ID is used to identify each device. You can assign logical IDs to each device.

When using multiple child devices for one parent device, assign different IDs (1 to 100) to each child device.

x: Transmission Output and Retry Count

You can weaken the transmission output to narrow the effective radio transmission range. However, power consumption does not change, so normally use the maximum output.

Retry count refers to the number of additional transmissions per one transmission request. Setting retry count may improve data arrival rate in poor communication environments. However, communication time and power consumption increase accordingly.

In interactive mode, input a two-digit number.

• Tens place: retry count
  • 1 to 9 times
  • 0 is the default value for each app
  • F disables retry
• Ones place: transmission output
  • 3 is the strongest
  • 2/1/0 each step down reduces output by -11.5dB

Examples

• 32 → Retry 3 times, output one level weaker
• 93 → Retry 9 times, maximum output

Resetting Settings

Some settings may interfere with operation (such as baud rate changes).

You can reset settings by the following steps.

1. Rewrite to another app
2. Switch to interactive mode
   • Reset with R
   • Save with S
3. Write back to the original app
