We’ve recently received a flood of inquiries about light gateways, furthermore, we’ve found that misconceptions pertaining to the light hotspot arising from people listed below:

To begin, Helium has publicly stated its intention to release a light gateway in early May, which we can interpret as a software-based light gateway. In terms of hardware, it is identical to the current full gateway, but it incorporates the following two major software features:

1.Block synchronization is no longer required;

2.Removed the relay status (a public IP address is no longer required);

That is, for a period of time in the future, the so-called light gateway will continue to manage the hardware configuration and run the light gateway’s software. We have completed the necessary tests and will push the automatic upgrade package following the official open update for helium.

And because everyone is interested in the light gateway at the hardware level (because it is less expensive and easier to deploy), based on the progress of the 2022 Status tracker: HIP19, no manufacturer has yet completed all of the light gateway’s certification requirements, implying that the hardware version of the light gateway should be opened only after the software is completely stable.

We are fully prepared to open the sales channel for this version of the light gateway (HT-M7603) immediately upon the official release of Helium.


Helium has officially disabled the V1 API, and devices that were not activated prior to April 18 may be unable to activate or update the miner image. We will distribute targeted updates to these devices to address this issue.

However, a very small percentage of devices may be unable to receive our push notification due to network issues, etc., or there may be a problem with the miner version not being updated; in this case, please contact support@heltec.cn.


Dear Sir or Madam, we appreciate your continuing support of Heltec as we strive to provide our customers with an improved product experience. we’ve also optimized our product delivery cycle in the new year; beginning February 25, new orders will be eligible for expedited delivery, with a three-week turnaround. Please contact our sales team immediately as quantities are limited.
Customers who have previously placed an order are also entitled to an earlier release date, though the precise date is dependent on our shipping notice.


Respected customers

Hello. To improve regulation of hotspot device layout, the helium official community recently implemented a series of management measures, including restrictions, prohibiting the use of equipment previously provided by a variety of equipment suppliers with known issues.

Additionally, we have initiated an investigation into the aforementioned irregularities. We discovered a large number of violations in previously manufactured CN470 devices, which is not what we wanted to see. To ensure compliance with Helium The People’s Network’s guidelines and to safeguard the interests of our customers. We have decided to suspend the manufacture of new CN470 devices.

We welcome everyone’s active supervision in order to maintain the health and stability of the Heltec community.

With the Heltec Indoor Hotspot’s rising exponentially global demand, we at Heltec are pleased to announce our latest distribution partnership with the companies listed below, which will serve independent Heltec Hotspot retailers in their respective areas.

The names of distributors:

All of these corporates are IoT device and communications value-added vendors who are identified as strong and highly regarded leading firms. Their product portfolio includes diverse and proven solutions from industry-leading global resellers. Their success is based on their ability to form strong partnerships with suppliers that result in positive outcomes for clients. They all operate in their respective regions, ensuring that they can provide a solid combination of international expertise and local knowledge. Their local warehouse footprint enables the depth of capability, putting Heltec in an excellent position to manage and deliver projects for our customers.

To successfully increase the brand awareness in the Australian, Asian, and European markets for growth sales, as well as providing services such as optimal installation and maintenance of the hotspot both face to face and remotely, we recommend that you directly inquire and purchase from those distributors outlined above.


Regarding the receiving sensitivity of some devices, we have been attaching great importance to it recently and have been doing related tests and experiments. Compared with other miners using SX1302 chipset, SX1308 has the following differences:

1. The receiving sensitivity of SX1308 is lower than that of SX1302;
2. In the reference design of SX1308, the FEM chip used is SE2435L, while the recommended FEM of SX1302 is SKY66420-11. The SE2435L has lower amplification gain and higher noise figure;
3. SX1308 will generate a lot of heat during operation, this will cause the center frequency shift.

Combining the above reasons, the receiving sensitivity will be about ~5dB lower than other machines using the SX1302 version. Antennas and coaxial cables may affect the overall receiving sensitivity.

Why should we choose SX1308?

We started preparing for the Helium project in April 2021. Under the circumstances at the time, SX1308 was the least likely to be out of stock.


  1. We will incorporate the temperature drift into the RSSI calculation in the V1.2.8 update;
  2. We are developing and testing filters and two-way signal amplifiers that can be used to correct the problem. This device can correct the inherent deficiencies of SX1308 in hardware;
  3. Starting from December 2021, this problem has been improved on newly produced miners;
  4. We are applying for a new generation of Hotspot based on the SX1302/3 baseband chipset.

If you have any questions about such issues, please send an email to xiaohong@heltec.cn for feedback and consultation. Your data and feedback are very important to us.


As the Helium network becomes more and more popular around the world, the block height continues to increase. Recently, we have received a lot of feedback from customers about the slow synchronization of the blockchain, which will lead to problems such as the reduction of the entire hotspot activity. In response, we have launched an OTA update of version V1.2.4 to solve this problem.

After this update is activated, please observe your devices more. If you still have any questions, please feel free to contact us.


As the cost of chips, components, materials, and so on has risen dramatically, the price of the Heltec Indoor Hotspot will rise by 40 US dollars beginning November 25th, bringing it from 459 USD to 499 USD (retail price). Please keep yourself up to date.


After the V1.1.7 patch was released this morning, many machines have been synchronizing, disconnected, etc. This is because Heltec Indoor Hotspot downloaded the latest blockchain mirror from the latest URL and is synchronizing.

Don’t worry, all you can do is wait for the synchronization to complete.


Recently, some customers reported that the machine only has the white LED light and the power light on. In this state, the machine cannot connect to Bluetooth, and some functions of the miner may not work properly, etc. Some functions hang.

The main reason for this situation is that the power source of Heltec Indoor Hotspot was forcibly cut off (unplug the power cord directly), resulting in garbled characters in the miner-related configuration files stored in the eMMC. If you encounter this situation, please ensure that the Heltec Indoor Hotspot’s network and power are normal, and send the Heltec Indoor Hotspot’s name or Mac address to support@heltec.cn, then our engineers can help you fix this problem remotely.

We have dealt with this kind of problem in the update file, but that still can’t completely prevent the file damage caused by forced power failure, so if you need to shut down, please press and hold the power button, do not directly unplug the power cord!!!


Suspend the use of HNT as a payment method. Accept USDT as a payment method.

Because the price of HNT fluctuates so much that we often encounter situations like this: For example, yesterday the price of HNT was 22 US dollars, but today suddenly reached 30 USD, then the customer who paid $22 yesterday asked for a refund. After the refund was completed, then placed an order again and traded at a price of $30.

This situation will greatly increase our workload, so we changed to accept the more stable USDT as the payment method.


It is very unfortunate to announce that we will stop accepting bank transfers as a payment method for limited-time purchases on our website.

As the bank informed us, wire transfers only support remittance from corporate accounts, not personal accounts. As a result, numerous online and offline orders have yet to be confirmed to the account for such a long period of time.

We sincerely apologize for the inconvenience.

In the meantime, We will also make an effort to contact customers who have already paid by bank transfer for a refund as well as negotiate for any other payment options. For these customers who adopt the new payment method, we will guarantee the originally planned delivery time.
