Ble stack server receiverlink loss

[balaji]

But in button event handler.

i want data to read from eeprom through i2c bus. and send it

through bluetooth stack for every press of buuton 0.

but in master control panel ,its says bluetooth connection loss ,once i press button 0.

Kindly tell me is it not possible to access i2c in button even handler.

static void button_event_handler(uint8_t pin_no) { switch (pin_no) { case HR_INC_BUTTON_PIN_NO:

//m_cur_heart_rate += HEART_RATE_CHANGE; m_cur_heart_rate = data2; dataW1[0]=dataW1[0]+2; twi_master_transfer(addw, dataW1, 2, 1); twi_master_transfer(addr, data1, 2, 0); data2=(data1[0]<<4)|(data1[1]); break;

case HR_DEC_BUTTON_PIN_NO:

//m_cur_heart_rate -= HEART_RATE_CHANGE; //if (m_cur_heart_rate < MIN_HEART_RATE) // { // m_cur_heart_rate = MAX_HEART_RATE; // Loop back // } break;

default: APP_ERROR_HANDLER(pin_no); } }

Hi Hung Bui,

Thanks for your reply,

I am using twi_hw_master.c .

once i used your code , write operation to eeprom is not working fine.

can you give some more details.
