sd_ble_gatts_hvx error

[sam]

when i use sd_ble_gatts_hvx() to send data,it cause a HardFault error。 when i trace the sd_ble_gatts_hvx() function,it will run to 0x00016432,in there will be compare two data,which data at 0x00016478 (value is 0xDEADBEEF),and other data at 0x2000012c(value still 0x00000000)。

Is need i initial something solve the programe,made 0x2000012c value is 0xDEADBEEF?

Thanks!

Please have a look at this question. To see the returned error code you need to turn off optimizations:

Options for Target->C/C++->Optimization

Set it to Level 0 and put at breakpoint at APP_ERROR_CHECK(err_code); after you call sd_ble_gatts_hvx()

Unfortunately,sd_ble_gatts_hvx() do not return any code. while call sd_ble_gatts_hvx(),in this function body ,while it compare two data at 0x00016478（value is 0xDEADBEEF) and 0x2000012c(value is 0x00000000) is not equal,function will fetch HardFault_handler entry and directly goto HardFault_handler .

Thanks!

Could you upload your complete project so I can reproduce it here?

Did you find a resolution to this problem? I am also getting a HardFault when calling sd_ble_gatts_hvx().

@Nick I didn't hear anything from sam, but if you could add a new question with your project, or a private case in your MyPage I will look into it.
