NordicThingy 52 sample - BLE possibly not working?

luckylucg over 2 years ago

Good day everyone.

I'm trying to start ConnectIQ development with the NRF dongle and BLE API.

I'm trying to check if BLE scanning is working with the CoinCollector sample, but I fail to get any scan results.

Here scanning starts, the print is also logged in the debugger:

onScanResults should be called when it has found BLE devices:

However I'm not getting anything logged in the debugger, which probably means I'm not getting any scan results..?

I believe flashing the NRF dongle went fine, COM port also seems correct:

Any ideas? Thanks a lot!

If there is a flashing led on the dongle, unplug it and plug it back in, and then check to see if the comm port you uses in the sim changes. BTW, just tried with the newest nRFconnect Desktop for window, and the newest programmer and it worked fine,

GRRR****!@@#@# Again! This thing doesn't work with SDK 7.1.0!!! WHY!!????? Both Nordic apps crash when I start them wit SDK 7. No matter if the dongle is there or not. See: forums.garmin.com/.../bug-sdk-7-1-0-both-nordic-sample-apps-crash

With SDK 6.4.2 it seems to recognize the dongle, at least when I type in the port it doesn't display the error. No more than that though.

Both samples don't really do anything. I'm not even sure what am I supposed to see. I see: My Label 0.00. Tried to open all kinds of bluetooth devices nearby and hoped to see something, but nothing happened. How do these samples work?

For the Nordic samples to do anything, you really need a Thinky52. For the basic sample, you then use the menu key to start scanning. Earlier in this thread I posted a one line change to the BLE delegate (a println in "contains") so it will show you anything seen in the scan,

Both samples work fine for me, and have since the say they were released. I do have a Thingy52

The breakout where BLE was announced is here (2019), but the Thinky52 sample they show is a bit different than what ended up in the SDK: https://forums.garmin.com/developer/connect-iq/b/news-announcements/posts/adding-bluetooth-connectivity-to-your-connect-iq-projects

Here's the 6.4.2 sample for the Thing52 in the sim for the 965, after scanning, and then pairing with a Thingy52. Some data can be seen updating every second.

Wait a second!? Do I need two thingy things???? I have the nRF52840 dongle that just arrived today connected to the computer and BLE Settings set to use it's port. I thought I'll be able to see some "random" BLE devices' MAC address in the scan. I hope I won't need to buy another one, 'cause the shipping costs 3 times the dongle...

In that video from 2019 in oe of the slides there's this:

connectivity_4.0.0_usb_with_s132_5.1.0_dfu_pkg.zip

and the link: http://tinyurl.com/donglefw that is redirected to: https://github.com/NordicSemiconductor/pc-ble-driver/tree/release/4.0/hex/sd_api_v5 and in that directory there's a file: connectivity_4.0.0_usb_with_s132_5.1.0.hex

But on https://developer.garmin.com/connect-iq/core-topics/bluetooth-low-energy/ the link is to https://developer.garmin.com/downloads/connect-iq/connectivity_1.0.0_usb_with_s132_5.1.0.zip so which one am I supposed to use?

jim_m_58 over 1 year ago in reply to flocsy🤠

The zip is just a zip with the hex file inside. If I need to flash, I use the hex file I downloaded using the garmin link.

flocsy🤠 over 1 year ago in reply to jim_m_58

but which hex file?connectivity_1.0.0_usb_with_s132_5.1.0.hex orconnectivity_4.0.0_usb_with_s132_5.1.0.hex or maybeconnectivity_4.0.0_usb_for_s132_5.1.0.hex ?

BTW depends on which zip, because for exampleconnectivity_4.0.0_usb_with_s132_5.1.0_dfu_pkg.zip (the one from the video) has 5 files in it and none of them is hex. THere are dat and bin files in that zip.

jim_m_58 over 1 year ago in reply to flocsy🤠

If you download the garmin zip, it only has 1 file. The hex file. Use that
