In nRF5_SDK_14.0.0_3bcc1f7\components\libraries\usbd\app_usbd.c
if APP_USBD_CONFIG_LOG_ENABLED is put at 1, the compilation fail. It is solved by adding NRF_LOG_MODULE_REGISTER...
when i use sd_ble_gatts_hvx() send data to ble stack, after 300ms later ,i get the ble stack event BLE_EVT_TX_COPLETE , how i can reduce the time(300ms), let the data send...
how i can send data 1500byte per second，use the sd_ble_gatts_hvx(). because i send the first package use sd_ble_gatts_hvx() and 300ms later i get the BLE_EVT_TX_COMPLETE,...
After reading some older threads it seems to me that someday it must have been possible to update bootloader and application with one zip file.
Currently I'm using sd 132...
This is kind of a follow-on to the original question here: devzone.nordicsemi.com/.../
