Can't connect anymore #161

@raffaeler, What device are you using as adapter from nRF Connect for Desktop, is it the nRF52840 Dongle? |
@bihanssen yes, I am using the nRF dongle. Frankly I would exclude the timeout issue as I can instantaneously connect from Android / BLE Scanner without problems (and this was the case before the recent update). |
@raffaeler, yes, the recent update is most likely part of the change in behavior. The firmware made a switch from SoftDevice v3 to SoftDevice v5 on the device, which may cause slight differences in behavior and timing. The fact that it still works on Android does not exclude timing issues in the combination of the nRF52840 SDv5 and your device. |
Got it @bihanssen ... if the firmware is likely the issue, what should I do now? Downgrade? How? |
Best would be to find a way to make it work with the current version. As suggested, you could try different connection parameters, different nrf kits, or provide a sniffer trace for investigation (post on devzone for assistance). If all else fails you could try to use an older launcher and using the previous BLE app version v2.3.2, though I wouldn't recommend it as that means losing out on updates. |
That is the only nRF kit I have, sorry. This is a community project and that is a personal investment. BTW the devices I am using are merely rs232 adapters. They have very few settings (about 10) and, as I said, they works very well with either Arduino of from Android apps. |
The devzone support portal is located at devzone.nordicsemi.com. Troubleshooting the issue is hard as we don't have your type of device and so can't reproduce. A sniffer trace or some other mean to reproduce would be needed for more investigation. |
Version 2.40
Supported engine: nRF Connect ^3.4.0
Current engine: 3.4.1
I recently upgraded the application. Since then, I cannot connect anymore to a JDY-10 bluetooth module. This module is just a bluetooth serial module bridge with a very limited configuration.
The Mobile app BLE Scanner can correctly connect and exchange data with the device, therefore I excluded problems on the module itself.
The steps I do from the Windows 10 PC are:
nRF Connect immediately answer with "Error - Device disconnected".
