Bluetooth LE Console for NUS

[Vojislav]

I connected my device over BLE with the computer and currently using Bluetooth LE Console from Nordic. The Console is receiving data and that is good, but I do not know how to send multiple characters at once. It is only sending one or 2 char at a time. Does anyone have more experience with this?

I am using Ubuntu with NCS 1.5.0

Best regards,

Hi,

This example gives you access to the shell interface over bluetooth. I am not able to see only 1-2 characters being transmitted, at my end its between 1-20 bytes. Do you have a log showing the issue?

 

Kind regards,

Håkon

Actualy I could send multiple chars at once when trying to press more keys at once.


But I would prefer to paste or edit in the console some larger strings.

Due to the deps on python2 in "ble_console" I had issues running this one (I reported this py2 dep internally), so I went with two nRF kits, where one of them ran the pc-ble-driver connectivity firmware and connected through this script:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/shell/shell_bt_nus.html#bt-nus-shell-py

 

I can add your findings to the component as a feature request internally.

 

Kind regards,

Håkon

Hi Håkon,

Thanks for the answer, it would be great to have this feature working natively without external components. 

In the meantime, I will try shell_bt_nus.py with the external board. About that:
* will it work with the nrf52840 dongle or I need to use the dev kit with Jlink?

Best regards,

You'll need a device that is capable of running the connectivity firmware (precompiled found in the release: https://github.com/NordicSemiconductor/pc-ble-driver/releases), found in path:

/nrf-ble-driver-4.1.4-win_x86_64/share/nrf-ble-driver/hex/sd_api_v5/

 

there's a dfu package there, but I haven't tried this in combination with the shell_bt_nus myself.

Note that this script is old, and I had a more stable operation with "sd_api_v3" at my end, but this might not be required on your end. Just mentioning it as a side-note.

 

Kind regards,

Håkon
