ThinkNode M4: Balancing communication and power needs¶
How to Combine Meshtastic Devices with Power Banks? ThinkNode M4 provides the answer!
ThinkNode M4 is a groundbreaking multifunctional power bank that not only continues the portable power support function of traditional power banks, but also innovatively integrates Meshtastic communication module, LoRa long-distance wireless communication technology and a high-precision GPS module, providing users with a new decentralized communication and positioning solution.
As a Meshtastic device, it provides users with high-precision, low-power positioning and communication solutions.
It has built-in Semtech's LR1110 (supporting 868-915 MHz frequency band), Nordic's nRF52840 and GPS modules to ensure the performance and reliability of the device. Meshtastic devices support distributed Mesh networks without relying on gateways or the Internet. Devices are nodes to each other and can automatically expand coverage. It supports two-way communication, including real-time text messaging and location sharing, and can meet diverse communication needs, whether it is point-to-point or broadcast communication. Meshtastic is particularly suitable for field operations, disaster emergencies, and other network-free environments, providing users with stable and reliable communication guarantees.

Usage¶
Conducting hiking expeditions and scientific sampling activities in remote mountain valleys. The team utilised nodes equipped with ThinkNode M4 devices as Meshtastic relays to facilitate information transmission and location sharing. The extended battery life provided by the large-capacity batteries ensured reliable communication support for the team.¶
The following outlines the procedure for transmitting signals to the designated relay point.¶
Prepare two mobile phones with Meshtastic APP installed and two thinknode M5\M1\M2 devices.
Android App(Version 2.6.30)¶
First go to the app store to download and install the Meshtastic APP
Meshtastic APP Usage:¶
Same settings on the receiving side as on the transmitting side¶
After opening the application, tap ‘Scan’ and select the corresponding Meshtastic device to connect.
When the Meshtastic_xxxx device is searched, tap to enter pairing mode.
Enter this code(123456) on your cell phone(The default code for the ThinkNode M6 is 123456.).
Set LoRa frequency: Tap the settings icon, select ‘Radio Configuration’, then tap the ‘LoRa’ option. Scroll down to the “Add” column and enter the required value in the ‘Coverage Frequency (MHz)’ field corresponding to the desired frequency.
If two devices want to communicate, they need to join to the same channel, this time you need to select the fourth of the five options above, the other end of the phone needs to join to the same channel by scanning the code or entering the link, the channel can be customized name and so on.¶
After joining, the two devices can now chat in the first screen by selecting Group Chat.
iOS App：¶
Same settings on the receiving side as on the transmitting side¶
1)Open the app, tap Bluetooth on the home page and see the device you want to connect. Click on Pairing.
The default code for the ThinkNode M6 is 123456.
2)When the Meshtastic_xxxx device is searched, tap to enter pairing mode.
3)After successful Bluetooth pairing, You need to go to Settings and click on Lora Settings.
4) Set lora Region. and then scroll down to set the frequency. consistent with the previous settings for the region. Finally, check ignore MQTT and save.
5)Go to the information page, select a channel and a QR code will appear, use another device to scan this QR code to enter.
6)Join and start sending or receiving messages.
