is that possible to send the peripheral device data to bluetooth less desktop over ble

[sagarnayakm]

Hello,

In my project, I want to send the data from the ble device nrf52832 dev kit to a connected in-built Bluetooth desktop/PC. Some desktop doesn't have inbuilt Bluetooth and for that, so I used a third-party dongle(TP link dongle) that provides Bluetooth capability to Bluetooth-less desktop. I scanned the peripheral devices with a third-party dongle same as the in-built desktop/PC Bluetooth. next, successfully send the data from the peripheral device to the desktop/PC. but i want to develop a custom dongle to send/receive the data from peripherals devices as well as it provides Bluetooth capability to Bluetooth less desktop/PC.

I have tried the nrf52840 dongle and most of them say that it's not recommended for development and even it didn't provide any Bluetooth capability to the desktop as in-built. using nrf connect desktop app we can scan and connect the device but i need the same as the in-built Bluetooth.

So please let me know how can i achieve this.

Thank You.

hello,

Thanks for the reply,

yes I have changed it and I can able to send the data from the dev kit to the dongle whatever data I have sent is received in the terminal but if I send the next data it replaces the old data in the terminal i didn't receive it in next line and one more thing if i use sizeof() for data transmission to dongle first character gets truncated if strlen() the full data get received for next data it replace old data.

this is the updated code,

Did you try to just use:

err_code=app_usbd_cdc_acm_write(&m_app_cdc_acm,p_ble_nus_evt->p_data,p_ble_nus_evt->data_len);

Since the strlen() and sizeof() doesn't know how much of the data that is coming from this event, and what was left from the previous event.

Hello,

If I used that yes it's received properly but the data not printing in the next line it just replaced the old data even I tried to memset() the data buffer but still happened the same.

Thank You.

I don't understand what you mean. Can you perhaps share some screenshot of what you are seeing and what you expect to see?

Hello,

thanks for the reply,

see this screenshot is sending "hello" from the peri-central dongle  

and next, i am sending "hi" to the central device,

so it's not printing in the next line it just replaces the old data.

if it doesn't possible to do so can we print the data in notepad as hid example? already my peripheral device doing the same whatever the data receives over uart it prints in connected devices notepad like mobile phones/laptops.

so tell me can we do that.??

Thank you.
