Downlink test message or ACK not received by node

Hi kalon33, sorry for the delay. TinyGPS is the solution to go for (at least for me)

Downlink test message or ACK not received by node

Hi Rick, unfortunately not. It seems that the documentation on the Seeed LoRaWAN module is killing me again (so much for Chinese products) making it almost impossible to find the root cause of the problem of not being able to receive either confitmed message or a downlink message I will try to do succeed with an other device like the HopeRF (yes I know Chinese) or a Raduino a reltively new device also using the Semtech chip. I'll keep you informed on my progress. As it seems not

Downlink test message or ACK not received by node

Hi Jeroen, this is exactly what I did. The RX1 delay is set to 1000ms and the time-out is set to 10secs. I also diregarded the libraries as I found out dureing my struggle with this board that they are incomplete. So for so far I can see I did everything correct. To my knowledge the ACK is transmitted at SF9, with this SF I can reach a Gateway.

Seeeduino LoraWAN on the KPN network

Hi Rick, Yes, I succeeded in setting up this device. For me the code as provided which szijlmans did not work and it took me a lot of effort to find out why. These were my findings: - the documentation provided for the radiopart was different from the firmware version in it, but the guys from RHF did sent a newer version (3.1) just to find out that there is a setting for private and public networks. Unfortunately the libraries didn't include these so I had to modify the libraries and add a new command to set this 'network bit'. After this I was able to set this network bit and now it works perfectly and reliable with the KPN network. I must admit that the KPN LoraWAN coverage is very good in comparison with TTN or Sigfox, last weekend I even had coverage in a very rural environment. Next step will be sending data downlink. Best regards, Jan

Test uplink error: javax.net.ssl.SSLException hostname in certificate didn't match: != OR OR

After a lng struggle with managed hosting I succeeded in getting a first Lora device (Seeeduino LoraWAN /GPS) operation at the KPN network without any problems. I must admit, I got my learning curve with TTN (thanks for that). Comparing TTN LoraWAN, KPN LoraWAN and Sigfox I notice that with TTN and Sigfox I'm unable to get indoor coverage. With KPN I have indoor coverage SF12 - SF10. Location is Hengelo (7558RN)

Test uplink error: javax.net.ssl.SSLException hostname in certificate didn't match: != OR OR

When I tried the connection this morning I experienced the same, however using the url via a browser gave the expected result.

Test uplink error: javax.net.ssl.SSLException hostname in certificate didn't match: != OR OR

Due to some troubles on the LoRa nodes I am using I didn't use the developers portal the last month. When I tried to test the uplink message I got the same SSL error. A check with Yourhosting showed that their SSL implementation works. From the above I got the impression that this error is a new one, but it shure worked flawless one month ago. Can this be confirmed? As my trial period is about to end I would love to get it extended.

Seeeduino LoraWAN on the KPN network

Hi Bas, unfortunately not. I contacted both Seedstudio and RisingRF and got some support, but it seems to me that the module is not transmitting. As an alternative I used a Raspberry Pi with an Draguino hat to set up a TTN gateway (packetforwarder) and here I see an othe LoraWAN device sending but from my device I do not see anything. So I have a kind of a test environment and my next step will be to see if I can detect RF transmissions by uing a kind of Grid Dipper. I didn't anticipate to need so much time in setting up a LoraWAN evaluation.

Seeeduino LoraWAN on the KPN network

Hi Bas, I tested it upstairs. I have a house that is mainly made of wood, with some brick walls so I expected it to work. [img]8068ec1a-79d3-48d7-977f-31759bfa7c02.png[/img] I did run a test outside (see photo) but the device is still not seen. I see the LED of the RF module blink when transmitting.

Seeeduino LoraWAN on the KPN network

I'm using an 868Mc antenna (see photo). From the LoraWAN specification I understood that it only receives data after a transmit and that the the device has to be recognised by a basestation to enable a downlink message. Or is there an other way to see if it receives messages? Rgds, Jan

Seeeduino LoraWAN on the KPN network

Hi Bas, according to the manual the only way is via the Hex chars: Change LoRaWAN related AES-128 KEY. If wrong key is used, your LoRaWAN modem will be rejected by LoRaWAN server. Contact server administrator to know what key should use. All KEYs are unreadable for security, the one who forgets his KEY need rewrite with a new key. Format: Change network session key (NWKSKEY) AT+KEY=NWKSKEY, “16 bytes length key” eg: AT+KEY=NWKSKEY, "2B7E151628AED2A6ABF7158809CF4F3C" eg: AT+KEY=NWKSKEY, "2B 7E 15 16 28 AE D2 A6 AB F7 15 88 09 CF 4F 3C" Return: +KEY: NWKSKEY 2B 7E 15 16 28 AE D2 A6 AB F7 15 88 09 CF 4F 3C Change application session key (APPSKEY) AT+KEY=APPSKEY, “16 bytes length key” eg: AT+KEY=APPSKEY, "2B7E151628AED2A6ABF7158809CF4F3C" eg: AT+KEY= APPSKEY, "2B 7E 15 16 28 AE D2 A6 AB F7 15 88 09 CF 4F 3C" Return: +KEY: APPSKEY 2B 7E 15 16 28 AE D2 A6 AB F7 15 88 09 CF 4F 3C and: Use to check the ID of the LoRaWAN module, or change the ID. Read ID Format: AT+ID

Seeeduino LoraWAN on the KPN network

Hi Bas, Here I copied the code, the LoRaWAN library (cpp and h) and I attached a screendump of the device settings as in the Portal. To complete it you will also find a phote of my test set-up. I hope you can see what I missed. Best regards, Jan This is the code: #include char buffer[256]; char DevAddr[] = "14204CD7"; char DevEUI[] = "0059AC0000181CD6"; char AppEUI[] = ""; char NetworkSessionKey[] = "a9cf96069897c4ecc3e01fa9cf3c2941"; char AppSessionKey[] = "5c841b73dd8bfeca2e8b7ea3a884e770"; char AppKey[] = ""; #define LoraDeviceMode LWABP // LWOTA or LWABP #define LoraDataRate DR0 #define LoraPower 20 #define LoraPort 1 #define LoraADR 1 /* * AT commands * AT? AT+ID=? AT+ID=DevAddr, "" // Set new DevAddr AT+ID=DevEui, "" // Set new DevEui AT+ID=AppEui, "" // Set new AppEui AT+RESET AT+MSG="Data" AT+PORT=? AT+PORT=1 AT+ADR=ON / ? AT+DR=?
