Great! Thanks for reporting back your findings.

Hi Jørgen,

No NUS is not implemented on the AVR(hence my issues), it is using an HM-11 serial/Bluetooth module and is programmed in Arduino 'land'.

I was unable to connect to the Toolbox UART app (i believe this looks for the NUS service on the peripheral). I can connect via the nRF Connect App and see the data I want to receive in a notification, I can also connect in my nRF51 firmware, but was unable to get the data from the notification.

Upon much Googling I came cross this tutorial:

https://visualgdb.com/tutorials/arm/nrf51/central/

It seems to do what I require.. i.e use nRF as a master to send/receive data/commands from a BLE device not using NUS (the peripheral device used in the example utilises the same UUID's and data structure. so I'm hopeful this will do the job.

Tho problems persist, they are not really related to my original question.. so I'll start a new one.

Many thanks.

PaulP

Hi,

Did you implement the Nordic UART service on the AVR, or are you using some other proprietary service on the peripheral?

Are you able to connect the peripheral from nRF Toolbox UART app?

Best regards,
Jørgen
