I have a Notecarrier-F v1.3. I have it working with I2C using an Adafruit Feather M0 Express that is plugged into the Feather socket on the Notecarrier. My overall project uses an external Adafruit Metro M0 Express because there are various Arduino form factor shields involved. The Metro M0 has a Qwiic shield so my next step was to remove the Feather from the Notecarrier and attach a Qwiic cable between the Qwiic shield and the Notecarrier. I have assumed that the startup operations should work: notecard.begin(0x17, 0x20, Wire); notecard.setDebugOutputStream(usbSerial); … create a hub.set requ ..read more

Hi! We have implemented cloud functions in Firebase which are used to ingest data from Notehub. We’d like to use the Google Cloud route type to forward the event. Is it possible to provide the route with a refresh token so that the access tokens are changed up at a regular interval? If that’s not possible, is there some other approach we could use to refresh the token? 1 post - 1 participant Read full topic ..read more

Hi, using the USB in-browser terminal and tried to upgrade the firmware from 1.5.6 to latest (7.2.2). Here’s what I got: DeviceUID dev:864622040824290 (NOTE-NBNA-500) running firmware 1.5.6.13807 Hint: A newer firmware, notecard-7.2.2 (2024 Q2 Developer Release), is available. See Notecard Firmware Updates > firmware install latest * Error installing firmware: Error: Could not initate dfu.put: unknown request type: dfu.put {io}. Is this because this Notecard is too down-level (1.5.6) and needs a lower-level version (say, 3.X.X) to operate in DFU mode? If so, how does one upgrade the N ..read more

Hi all, I’m not sure if this is a support request or a minor bug report. I’m trying to set up a Route with a rate limit below 1 request per second. The field lets me increment the rate in steps of 0.000001 requests per second but if I set it to 0.05, events don’t seem to be routed at all. The route works fine if the request rate is set to 1. Is there something I’m missing or are the field limits just misleading? (The “requests per second” field also lets you input negative values, whereas the “Timeout (s)” one below restricts the input to integers >=0, so I’m guessing the latter.) ~Hazel 1 ..read more

The hardware: Swan - note carrier A - cellular card - programed with arduino. My application is a remote rain gouge. If there has been some rain in thee past @48 hrs. it sends a payload every 30 mins. The problem is it sometimes waits 3 hrs and then there is a; {“why”:“first sync; periodic inbound sync due”} {“why”:“first sync; periodic inbound sync due (TLS)”} {“text”:“boot (hardware watchdog & hard reset [16292] [3.0] G:POW)”,“voltage”:3.5527344} I remember reading somewhere how to open up the notehub.io so staff can take a look at it but can’t find it now. I can’t figure out why it keep ..read more

The original project was working well and I was receiving SMS from twillio. Now after cloning, I can see the twillio.qo in the events page of Notehub but I am not receiving the SMS. I copied and pasted the authorization token back into the route thinking maybe the password characters did not clone. Nope. I have plenty of money in twillio so that is not the problem. I checked the phone numbers and that is all correct. Could the problem be related to the clone? Thanks, Tom Edit to add: I tried the original project and it works ( I received SMS from twillio) so the problem is with the clone. 1 po ..read more

I have been following notecard documentation to work with BME280 sensor and upload weather data to Notehub using Notecard track mode. The documentation has explanation that in track mode, the device uploads data inside _track.qo automatically. But for me it is not working. dev.blues.io Working with the Notecard AUX Pins - Blues Developers Learn the various modes for using the Notecard AUX pins in your projects. The steps I took is following using the browser based cli. { “req”: “card.aux”, “mode”: “track” } Then do sync. { “req”: “hub.sync” } Unfortunetly the _track.qo file is not uploaded. ev ..read more

I’m trying to perform a web transaction as described here. I’ve set the route this way: Route name: post_test URL: https://posttestserver.dev/p/y1fyj8gy56w23i09/post Notefiles: Selected Notefiles: System Notefiles + barcode.qo Data:Transform Data: JSONata Expression: {“qr”:(body.qr)} This is my example data (sent using the web serial terminal connected by USB to the notecard): { "req": "web.post", "route": "post_test", "name": "/post", "body": { "qr": "test1" } } The response I get is this: { "result": 503, "body": { "err": "hub request error: notehub route with alias 'post_test ..read more

Is there a way to export the json configuration from the notecard/notecarrier device, or to do so remotely? The scenario is that once the notecard/notecarrier is deployed to the field, or once it is returned from the field, I would like to dump (export) the configuration to see exactly how it was configured when it was first deployed. 1 post - 1 participant Read full topic ..read more

Hi, I was wondering if there is a way to configure the notecard to work as a data-relay for instruments outputting rs232 / uart data. Many instruments output telegram style data (NMEA or similar), and just putting a notcard on and caching a bunch of these and syncing now and then would make it very easy to make these instruments work remotely. Bonus points for two-way communications. Would be very easy to do with an MCU in probably less than 20 lines of code, but it would be even greater if I could just skip the MCU and the notecard supported this.
