BLED112 from silicon lab to connect using Bluetooth Low Energy

[m.daldo]

I want to know if I can use the dongle BLED112 with the bluetooth low energy app.

If not, which one should I consider?

I am trying to replicate the experience given by the phone to connect to a bluetooth device and be able to change some configuration of the device itself.

Thank you for the support.

Dear Edvin,

I am currently experiencing intermittent connection issues when attempting to interface with a BLE sensor using the Nordic BLE application. The connection attempts either fail, succeed temporarily, or cause the application to freeze and disconnect unexpectedly.

Issue Summary:

• Repeated connection attempts often fail or result in temporary success before unexpectedly disconnecting.
• The application freezes and disconnects when interacting with certain device settings.

Detailed Timeline from Logs (attached):

1. 09:55  - Initial connection attempt failed.
2. 09:56  - Connection attempt succeeded.
3. 09:57  - Application froze and disconnected when attempting to edit device settings.
4. 09:58  - Subsequent connection attempt timed out and failed.

System and Configuration:

• nrf-device-lib-js version: 0.4.4
• nrf-device-lib version: 0.10.3
• nrfjprog DLL version: 10.15.1
• JLink version: JLink_V7.66a
• BLE connectivity firmware version: 4.1.4+Mar-11-2021-08-36-04
• SoftDevice API version: 5
• Baud rate: 1000000 (no flow control or parity)
• Adapter: COM5

Observations and Setup:

• The device and adapter settings were initialized without errors, and the UUIDs were updated from the official Nordic GitHub repository.
• Issues seem to arise during device interaction post-initial setup, with repeated connection attempts not resolving the problem.

Could you please assist in identifying potential causes for these connection stability issues? Any insights or recommendations on configuration adjustments or firmware updates would be greatly appreciated.

Hello,

Based on the logs it looks like a timeout disconnection, and it looks like it comes from the other device stops responding. 

From your screenshot it looks like you are paired/bonded, and from the logs you are paired, and not bonded. Did it bond or pair when you did this with your phone as well? Did you experience the same issues when you did this with your phone?

I also see from your screenshot that the characteristics are loading. Try waiting a couple of seconds between the connection and trying to load the characteristics. Does that help?

BR,
Edvin
