Xiaoling 1.2 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.
Xiaoling 1.1 10
Xiaoling 1.2 11 Dragino has different gateway models that support different types.

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

64
65 Install the Helium gateway-rs
66
67 Note: User will see the echo characters of Helium gateway-rs have been installed successfully.
68
69
70 == Step 4: Save&start the Helium Server ==
71
72 Click **Save&Apply** and gateway will start to connect the Helium. The UI shows the connect status.

75
76 Start Helium-gateway-rs
77
78
79 == Step 5: Check Gateway Connection before onboarding ==
80
81 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.
82
83 Check end device event from [[Helium Console>>url:https://staging-console.helium.wtf/]], We can see the LGT92 data arrived Helium via our hotspot.
84
85 [[~[~[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]]
86
87 Check if the packet is transferred via LPS8
88
89 **Note:** The hotspot is not valid for search in Helium Console before onboarding.
90
91
92 == Step 6: Onboarding Data-Only Hotspot ==
93
94 Note: Onboarding a Data-Only hotspot is not necessary, and it will gain very, very small awards on HNT by data-transfer .
95
96 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.
97
98 Below are the steps we do as per above link here.
99
100 ~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.
101
102 {{{[root@iZt4n22vqvm7ajogrfiif6Z helium-wallet-v1.6.4-x86-64-linux]# helium-wallet info

125
126 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.

130 We got the txn info from this step.
131 \\3. Add Hotspot. In the computer with helium wallet. run below command, replace the txn with the txn you got in above step.

222 Note: The add hotspot and assert location step might need some time to be effect.
223
224 After above steps finish, the mobile helium wallet should be able to show that this hotspot has been added to the helium blockchain.

227 == Debug Connection ==
228
229 === Check pkt-fwd running Log ===
230
231 This command can check if the LoRa Radio part runs correctly and if the gateway receives LoRa packets from LoRaWAN sensors.

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.

286 The Dragino gateway has supports the double server settings.
287
288 Users can back to the page of Semtech UDP to configure other server settings.

363 == How to send a downlink to end device from Helium ==
364
365 The Helium server needs to convert to Base64 format when sending the downlink command. Please refer to the following example:
366
367 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]]

444 == Trouble Shooting ==
445
446 === Trouble to Join Helium ===
447
448 Assume the device is powered correctly. If you don't see data in Helium. The possibilities are:
449
450 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)
451
452 2) Your end node frequency band doesn't match the Helium gateway frequency band. (Please double-check if frequency band matches)
453
454 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)
455
456
457 === Packet Loss for AU915 / US915 Band ===
458
459 The node working on the AU915/US915 frequency has packet loss or the frequency channel and the gateway channel are different.
460
461 The reason for this problem is that the node does not lock the channel after joining the network.
462
463 Solution:
464
465 (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.
466
467 * AT Command: AT+CHE
468
469 * Example:AT+CHE=1 ~/~/set channel mode to 1
470
471 * Downlink Command: 0x24
472
473 Format: Command Code (0x24) followed by 1 bytes channel value.
474
475 If the downlink payload=2401, it means set channel mode to 1, while type code is 24.
476
477 * Example 1: Downlink Payload: 2401 ~/~/ set channel mode to 1
478
479 * Example 2: Downlink Payload: 2405 ~/~/ set channel mode to 5
480
481 (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.
482
483 The latest firmware for end node will have this bug fixed.
