Hi Everyone, Has anyone achieved Class B and C Functionality of LoRaWAN Uptill now ?? Which available gateway supports all LoRaWAN device classes ??

I haven’t seen any device yet that supports B or C. Also, the current TTN testbed does not yet support this.

TTN doesn’t even fully support class-A yet as far as I know the following is still missing: no confirmed sending (yet) meaning that the node gets an acknowledgement from the gateway the packet successfully arrived. no dynamic over the air pairing of nodes (yet), only static (activation by persona…

Well, Semtech’s reference implementation supports class C devices, and IBM’s LoRaWAN in C partially supports class B devices. While Microchip’s RN2483 only supports class A devices, there are plenty of modules available that give direct SPI access to the SX1272/SX1276 chip allowing you to run these…

Hello, It’s been one year already and I was wondering if there has been some progress on the implementation of Class B and C devices. I am particularly interested in implementing a Class B end-device. I don’t know if my inAir9B supports Class B directly or needs a firmware update. Also, where can I…

I don’t think class B and C will be implemented. See: [image] SWOT Analysis on TTN Hi @hoonppark , I think your analysis is very accurate. It’s very helpful for us to see what we’re doing right and where we should improve. Some comments / background: TTN Production Serv…

We are definitely going to implement Class B and C in our backend, but it’s not sure if we’ll be able to fully support this in the public community network.

Do you consider them as a pair or will class C be implemented separated from (before?) class B?

We intend to implement Class C first.

Class B require a precise synchronisation across the gateways. As the TTN network is made of various type of GW and not all of them will have access to a reliable time source (GPS receiver), the proper time synchronisation required by Class B will probably not being available.
