Will you migrate this tutorial to SDK 15 and nRF52840?

That was quite a well structured post with a realtive good insight on how SDk nordic works. My only remark would be that you repair the broken links[emoticon:98f842990f454422aa6a04953955f9d9]. thanks!!!

This tutorial could be enhanced by telling the readers where in NUS they could add their own Rx packet parsing.

Thanks for nice tutorial. Very helpful in understanding Flow.

I am facing some issue, I am using HM10 ble module as peripheral and NRF52832 (Redbear NANO v2) as central device. I using SDK "nRF5_SDK_12.3.0_d7731ad" and example program "nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\ble_central\ble_app_uart_c". I changed UUID's according to HM10 service and char UUID here "NUS_BASE_UUID, BLE_UUID_NUS_SERVICE, BLE_UUID_NUS_TX_CHARACTERISTIC, BLE_UUID_NUS_RX_CHARACTERISTIC". When I flashed code in chip and tried to run in my serial terminal I am getting

"Uart_c Scan started Connecting to target b5c81319fdc8 Connected to target Starting discovery of service with UUID 0xffe0 for Connection handle 0

Uart_c Scan started Connecting to target b5c81319fdc8 Connected to target Starting discovery of service with UUID 0xffe0 for Connection handle 0

Uart_c Scan started Connecting to target b5c81319fdc8 Connected to target Starting discovery of service with UUID 0xffe0 for Connection handle 0"

and so on.......... in a continues loop

Why this is not stopping after it finding peripheral and not moving for TX RX communication.

-Is this code is only designed for to connect only with NRF5832 chips? -Can I connect to any generic BLE peripheral device using "ble_app_uart_c" example?

Waiting for reply soon

Thanks in Advance.

Hello Nordic, Its seems like nobody has same problem as me. But when ever I try to run examples involving the ble_stack_init() function it stucked in there, newer coming out? maybe waiting for an event or something?. Help is very much appriciated.

Is it possible to use the example ble_uart_c with our custom UUID service from exampleble_app_template? If so, which portion of ble_app_uart_c example code, should we need to change to make it available to connect the Central device to peripheral device using the custom service and display the data that sent from peripheral to PC's serial monitor?

First many thx for tutorial! But I found issue when testing it with putty terminal. It seems that my putty for some reason does not send "\n" on enter but only "\r". Thus it seems example did not work unless you wrote too many characters. If you have same problem just comment line:

//if ((data_array[index - 1] == '\n') || (index >= (BLE_NUS_MAX_DATA_LEN)))

This way it will send every character immediately.

I recommend to nordic to use it in example to make it stupid terminal resistant...

Thank you. It helps a lot.

I wish Nordic make more tutorial and Youtube tutorial. :-)

Really nice tut! Is there a similar Tutorial for SDK11? When i go through the Service discovery part, there are many sections with differences to the SDK11 for example

old SDK10:

return ble_db_discovery_evt_register(&uart_uuid, db_discover_evt_handler);

new SDK11:

return ble_db_discovery_evt_register(&uart_uuid);

Thank you for the effort I found it extremely useful. In the connecting section you are refering to:

p_ble_nus_c->conn_handle = p_ble_evt->evt.gap_evt.conn_handle;

but the SDK line and also ble_evt_dispatch() use

m_ble_nus_c

Is it just a typo or could you please bring the light to it?

It seems that all the references to "ble_uart_c.c" are actually meant to point to "ble_nus_c.c" in all of the SDK examples (the GitHub project does have the file "ble_uart_c.c".
