I want to send a set of 64 bytes data with ble. as I understand, the max data length I can send within a characteristic is 29 byes. when I send 4 bytes data it works fine...
Is it possible to bit bang a 9600 baud UART on the nRF51822 while the BLE softdevice is running?
The reciprocal of 9600 baud is around 100 µs, so the interrupt handler...
Hi Team,
