Hi,

I am very sorry for the delayed response.

I am afraid I do not have any experience with the device that you mentioned. First and foremost we recommend our own DKs and Dongles, as those are what our firmware is originally made for. Other nRF devices might require modifications to the firmware (depending on what pins they use for UART), J-Link programmers in order to flash the firmware, etc. but that is all dependent on the board in question.

I think it could at least be worth having a look at the nRF52 Dongle, which is intended for exact this purpose of connectivity device.

For nRF development I recommend to use at least one nRF52 DK, as it is supported by our SDKs (including the nRF5 SDK for Mesh) and comes with a J-Link programmer that can be used to program other boards during development. You may of course find other boards out there as well, that better suits your specific needs.

Regards,
Terje

Do you know if there is firmware that could be flashed to this device to make it usable as a dongle? I looked for your dongles online and it seems the distributors don't have them in stock. And which of your dongles has the most capability and/or newest architecture? I'm interested in experimenting with Bluetooth Mesh.

Well I guess that's the problem—somehow I missed the fact that external hardware is required! Is there something you recommend for a Mac? This is basically for hobby & independent development so I'm not looking for something expensive.

Hi,

From what I can see that is the same log as previously, just without the Segger J-Link errors.

I do not see any log entries for trying to establish serial port connection to a local device. What device are you using for connectivity, does it list properly in the "Select device" dropdown, and does anything fail if selecting it? nRF Connect for desktop doesn't use BLE hardware on the computer itself, rather it uses an nRF DK or Dongle for providing BLE capabilities.

Terje

Sorry, still doesn't work after installing 6.22g and removing the newer version. I launch nRF Connect, then click the Launch Bluetooth Low Energy button. The "Start scan" button is still grayed out/disabled. I verified that the Mac's Bluetooth is on.

The log is different this time: instead of complaining about a DLL it now complains about serial numbers for serial ports(?)

Hi,

I recommend version 6.22g because that is the latest version known to work flawlessly with nRF Command Line Tools. (There were some issues there lately, with the newest J-Link drivers.)

When you have installed the J-Link Software and Documentation Pack nRF Connect should work. If you are still seeing problems with it, please provide the logs and full description of what you do and what version of the J-Link driver you are currently using.

Regards,
Terje

OK, first I'm trying the current version, 6.32h. Is there some reason to use the older version?

What now?

Hi,

The file ending .dll is most known for Windows, yes, but dynamically linked libraries are used on all platforms.

Can you try downloading and installing version 6.22g of the J-Link Software and Documentation Pack, from Segger?
