Hello, if I disable interrupt on nrf51xxx device, function sd_ble_tx_buffer_count_get will simply run right into hard fault handler, without returning anything.
I do not "HAVE TO" disable the interrupt when executing this function but the entire logic of my program became really dicey if I keep the interrupt available all the time when calling a function that invoke sd_ble_tx_buffer_count_get.
So my question is:
1st: (the silly one) what may caused this problem? 2nd: Is there a workaround? Note that if there isn't, it's no problem, I'll simply modify my code, but still I am quite curious.
Thank you.
