7 == 1.1 Support Models ==
8
9 There are three types of hotspots that can connect to Helium. They are full-hotspot, light hotspot and data-only hotspot. Definition of these three types of hotspots can be found here: [[of Helium Hotspots>>url:https://docs.helium.com/mine-hnt%7CTypes]]. Different hotspots support different mining abilities.
10
11 Dragino has different gateway models that support different types.

60 == Step 3: Install the Helium-gateway-rs ==
61
62 Click **Install Helium Server** to install gateway-rs.

65
66 Install the Helium gateway-rs
67
68 Note: User will see the echo characters of Helium gateway-rs have been installed successfully.
69
70
71 == Step 4: Save&start the Helium Server ==
72
73 Click **Save&Apply** and gateway will start to connect the Helium. The UI shows the connect status.

76
77 Start Helium-gateway-rs
78
79
80 == Step 5: Check Gateway Connection before onboarding ==
81
82 A hotspot can transfer data to Helium after finishing step4. We can add a device to Helium and see if the device can join Helium. For example, we add an LGT92 sensor and see below info.
83
84 Check end device event from [[Helium Console>>url:https://staging-console.helium.wtf/]], We can see the LGT92 data arrived Helium via our hotspot.
85
86 [[~[~[image:https://wiki.dragino.com/images/thumb/c/c4/Data-hotspot-data_1.png/600px-Data-hotspot-data_1.png~|~|height="192" width="600"~]~]>>url:https://wiki.dragino.com/index.php/File:Data-hotspot-data_1.png]]
87
88 Check if the packet is transferred via LPS8
89
90 **Note:** The hotspot is not valid for search in Helium Console before onboarding.
91
92
93 == Step 6: Onboarding Data-Only Hotspot ==
94
95 Note: Onboarding a Data-Only hotspot is not necessary, and it will gain very, very small awards on HNT by data-transfer .
96
97 User can refer [[this link>>url:https://docs.helium.com/mine-hnt/data-only-hotspots]] for how to onboarding a data-only hotspot. After onboarding the data-only hotspot, user can see the hotspot on Helium Console.
98
99 Below are the steps we do as per above link here.
100
101 ~1. Set up Helium-Wallet in my computer. [[https:~~/~~/docs.helium.com/wallets/cli-wallet>>url:https://docs.helium.com/wallets/cli-wallet]]. and funds this wallet. From this step, we got the wallet info as below.
102
103 {{{[root@iZt4n22vqvm7ajogrfiif6Z helium-wallet-v1.6.4-x86-64-linux]# helium-wallet info

124 Note: The wallet Address is 13oLxfjxcYajvfkxxxxxxxxxxxxxxxxxxxxxfY3yp4cz8r1NNux. and have about 18 HNT balance.
125
126
127 2. Get txn. In the data-only hotspot. run below command to add a hotspot, owner is the owner wallet of this hotspot, payer is the payer to pay transaction cost.
128
129 {{{root@123123:~# helium_gateway add --owner 13oLxfjxcYajvfkxxxxxxxxxxxxxxxxxxxxxfY3yp4cz8r1NNux --payer 13oLxfjxcYajvfkxxxxxxxxxxxxxxxxxxxxxfY3yp4cz8r1NNux

138 }}}}
139
140 We got the txn info from this step.
141 \\3. Add Hotspot. In the computer with helium wallet. run below command, replace the txn with the txn you got in above step. Note, below are two commands, the command without ~-~-commit is the preview mode. Check every detail in this mode and run the command with ~-~-commit to commit to the Helium Blockchain.

232 Note: The add hotspot and assert location step might need some time to be effect.
233
234 After above steps finish, the mobile helium wallet should be able to show that this hotspot has been added to the helium blockchain.

237 == Debug Connection ==
238
239 === Check pkt-fwd running Log ===
240
241 This command can check if the LoRa Radio part runs correctly and if the gateway receives LoRa packets from LoRaWAN sensors.
242
243 Below logs shows the gateway receive two LoRaWAN packets.

And once the uses upgrade the gateway or the gateway lose the key, the gateway-rs will generate a new key for which the data-only hotspot is the new unit. so if the user would restore to last time which can upload your backup key to the gateway by the button of upload.

300 The Dragino gateway has supports the double server settings.
301
302 Users can back to the page of Semtech UDP to configure other server settings.
303
304 === Example ===
305
306 The following takes The Things Network as another LoRaWAN server as an example,

377 == How to send a downlink to end device from Helium ==
378
379 The Helium server needs to convert to Base64 format when sending the downlink command. Please refer to the following example:
380
381 The Downlink command comes from this link：[[https:~~/~~/wiki.dragino.com/index.php?title=End_Device_Downlink_Command>>url:https://wiki.dragino.com/index.php?title=End_Device_Downlink_Command]]
382

458 == Trouble Shooting ==
459
460 === Trouble to Join Helium ===
461
462 Assume the device is powered correctly. If you don't see data in Helium. The possibilities are:
463
464 1) You are out of Helium Gateway coverage. (If you have other end nodes, you can check whether they work and what is the signal strength you see in the platform)
465
466 2) Your end node frequency band doesn't match the Helium gateway frequency band. (Please double-check if frequency band matches)
467
468 3) You have input the wrong keys into Helium Platform ( You can send us the screenshots for the keys and Dragino support team can check for you)
469
470
471 === Packet Loss for AU915 / US915 Band ===
472
473 The node working on the AU915/US915 frequency has packet loss or the frequency channel and the gateway channel are different.
474
475 The reason for this problem is that the node does not lock the channel after joining the network.
476
477 Solution:
478
479 (1)If the user does not have a device to upgrade the firmware, you can use the AT+CHE command or the downlink command to set the channel. It is best to turn off the adaptive rate (ADR).Reset the device after setting the channel.
480
481 * AT Command: AT+CHE
482
483 * Example:AT+CHE=1 ~/~/set channel mode to 1
484
485 * Downlink Command: 0x24
486
487 Format: Command Code (0x24) followed by 1 bytes channel value.
488
489 If the downlink payload=2401, it means set channel mode to 1, while type code is 24.
490
491 * Example 1: Downlink Payload: 2401 ~/~/ set channel mode to 1
492
493 * Example 2: Downlink Payload: 2405 ~/~/ set channel mode to 5
494
495 (2)If the user has a device to upgrade the firmware, it is better to upgrade the device to the latest version. The latest version has fixed the problem that the AU915/US915 frequency does not lock the channel.
496
497 The latest firmware for end node will have this bug fixed.
