How can i send fix more than 20 element size of array in BEL nus in nrf52?

[ram]

Hello,

I am using nrf52 for my project. i need to read sensor value for 20micro second in array. I need 10000 reading in array to check condition. but array size more than 20 is not working.

Thank you,

NUS provides unstructured data packets. If your protocol running on top of it supports it then just cut your data into 20-byte blocks and keep sending. If not then you need to come up with your proprietary fragmentation/defragmentation layer and formatting (some kind of header).

Almost a duplicate question. Either amend your original question, or delete it and ask it again. But avoid asking the same question twice. See duplicate question and answer here devzone.nordicsemi.com/.../

the source code for NUS is available. You can modify it to send bigger packet. Softdevice will beak it down to multiple MTU size packet.

Actually it working for nrf51 but not for nrf 52. because function is not found. ble_attempt_to_send devzone.nordicsemi.com/.../ in this example function ble_attempt_to_send not found for nrf52. I an using SDK nRF5_SDK_13.1.0_7ca7556. i am using nrf 10040 nrf52832 s132 Development board.

Where i found this function for nrf 10040 nrf52832 s132.

Thanks

Ram.

ble_nus_string_send is used to send packets in the nus project. Or just make your own function to do this. The SD function is called sd_ble_gatts_hvx
