Role of nRF51822 in connectable and undirected advertising mode

[satheesh]

Hi Friends,

I am using nRF51822(S110 and SDK10.0.0) in my project and I need the chip to be in connectable and advertising mode under peripheral config . I configured the device to my requirement. I needed to write a data to chip using mobile app. But found the service available is only to read. Can I write a data from mobile app and if Yes any example programs.

Thanks.

How did you configure it? Did you make the characteristic value writable? What app are you using? You can have a look at ble_app_uart example. Examine tx_char_add(). There you can see that the characteristic properties allow write request (char_md.char_props.write = 1;) and write command (char_md.char_props.write_wo_resp = 1;). You also need to allow write access to the attribute, this you do with BLE_GAP_CONN_SEC_MODE_SET_OPEN(&attr_md.write_perm);
