[james tech]

hi nordic;

i need your help, i'm trying to code a control of gpio over the BLE i have an app on android with it i can establish connection and see the service and charactrestic but the problem that i have, is with event on_ble_write i want juste change the state of the pin 20 on my nrf51822 pca20006 just after receiving any kind of data but it didin't work .

to recap the idea of the code attached i have function returnei returnes a variable ii after sending some data from smartphone to nrf over ble this variable intially is at value 2 after sending the data its value will be at 0 and the pin 20 will be at low state but unfortunately this didn't work

any help from you will be appreciated

1. Have you debugged your code and checked whether on_ble_write() is being called and whether ii is being updated?
2. What SDK are you using?
3. Try to declare ii as 'volatile'.

thank you the problem is with the nature of the variable I must declare it volatile
