Problem with nrf51-ble-app-temp

[Paolo A.]

Goodmorning

I have few problem with this project. I took the source file from github.com/.../nrf51-ble-app-temp and I modified the main.c to use with S110 6.0.0, nRF51 SDK version 6.0.0 and nRF51822 Evaluation Kit (PCA10001) version 2.2.0. For temperature with the function sd_temp_get(&temp), I have an error code = 15 (forbidden operation-> Tried to write to or read from protected location). Furthermore, after I have put errorcode = 0, in the place of sd_temp_get(&temp) function and temp = 0, the PCA10001 seems to work, but I can not connect the EK to nRF Temp 2.0 app on my smart phone. So, there is something that I don't understand. Can you help me, please?

I remember you that I use Keil uVision 5.0 for compiling the project. Is there any setup to do in this development tool?

Thanks

P.A.

Hi John your suggestion was very helpful. With SDK 7.0.0 is necessary enable BLE with sd_ble_enable in ble_stack_init() function. I put below the code snippet:

// Enable BLE stack

ble_enable_params_t ble_enable_params;
memset(&ble_enable_params, 0, sizeof(ble_enable_params));
ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;
err_code = sd_ble_enable(&ble_enable_params);
APP_ERROR_CHECK(err_code);

where IS_SRVC_CHANGED_CHARACT_PRESENT is defined in main.c like:

#define IS_SRVC_CHANGED_CHARACT_PRESENT 0

Now the EK device works fine with app nRF temp 2.0. on my smart phone

Thank you very much
