About not getting complete notification data using nRF51 dongle and nRF Connect Desktop version

[Jones]

Hi,

I am using nRF Connect (Desktop) v3.3.0 with a nRF51 dongle with the latest firmware to test my BLE device application.

My application contains 1 customized service with 2 customized "Request" and "Response" characteristics. The idea is that the request message is written to "Request" characteristic, the device will send respond message from the "Response" characteristic through notification.

However, when the length of the response is longer than 20 bytes, the nRF Connect just shows 20 bytes.

I have use Android version of nRF connect to verify my application. It really send out message as expected (longer than 20 bytes).

Is it a limitation on nRF Connect (Desktop) / nRF51 Dongle?

Or I can do something to make the desktop version works?

Please let me know your comment. Thank you

Jones

Hi,

I tested this with nRF Connect, and it seems that I'm not able to send more than 20 bytes with nRF51. This should be possible by using the Queued Writes module in the SDK, but this may not be included in the connectivity FW used by nRF Connect.

Best regards,
Jørgen
