Not able to modify advertisement packet more than once, (without adv_timeout) on interrupt

[Brajesh]

Hi All,

My goal is to change the advertisement(when not "connected" to ble device) in every SPI Interrupt, depending on the data received i set corresponding data in advertisement packet. The small code snippet that I'm using, is given below.

spi_event_handler : ################################################################################ if (m_rx_buf[0]=='o') { if(connect) err_code = ble_nus_send_string(&m_nus, open_door_str, 10); else { open_door = 1; //sd_ble_gap_adv_stop(); open_door_adv_init(); advertising_start(); } } if (m_rx_buf[0]=='c') { if(connect) err_code = ble_nus_send_string(&m_nus, close_door_str, 10); else { close_door =1; close_door_adv_init(); advertising_start(); } } ########################################################################### The issue that i face here is i am able to change the advertisement packet on first interrupt, but advertisement packet doesn't change afterwards for later interrupts. But i need to change adv_data multiple times. I'm able to change the advertisement packet every time if i wait for adv_timeout. Although, when connected all the messages are sent regularly on every interrupt.

Can anyone please suggest me what's wrong with my method or above code snippet. Any suggestions or help would be appreciated.

Thanks Brajesh

Sounds, given this comment in your comments,

"it doesn't come inside the spi handler further"

that this has nothing whatsoever to do with advertising, it sounds to me that you only enter the above piece of code once, with either 'c' or 'o' as the first character, change the advertising and then either you never read another character, or every one you read is the same as before and so you change the advertising to be exactly the same each time.

You need to go work out why your spi handler doesn't get called again.

Thanks everyone for suggestions. Actually there was no issue with the code, the issue was i guess battery, when i connect my board to direct supply, advertisement change works fine absolutely, but if it is taking supply from even 10 days old battery, it doesn't change the advertisement every time although it does advertise last data.

I am facing similar kinda scenario in my other work, will be posing that query seperately. Thanks everyone again.
