hi all,in sdk10 i took heart rate central example of s130 and ble peripheral uart example of s110 v8.0 and i want to connect the both the devices central and peripheral

[prudhvi]

my question is how to change the uuid in central to connect to peripheral and i want to send 20 bytes to central device using this uart_peripheral. first of all my connection is not establishing b/w central heart rate and peripheral uart. iam using two nordic evaluation boards of nrf51822, keil ide,softdevices s130 v1.0 for central and s110 v8 for uart_peripheral

please help

thanks & regards, prudhvi

I have read that tutorial but clear description is not given about sending and receiving the data and from which api the data can be sent from central to peripheral. Actually my task is to send the data from central board to peripheral 20bytes and peripheral should recieve glow the led but I am not getting the data from peripheral please help me

Take a look at how this function is used in the example, and go from there

uint32_t ble_nus_c_string_send(ble_nus_c_t * p_ble_nus_c, uint8_t * p_string, uint16_t length);

thank you I got the output.

can we connect two peripherals to one central(s130 softdevice) device at a time

[Anders Strand]

yes you can connect uo to 3 peripherals. In the next version (v2), you can connect to 8.
