Hi,
I am sending data from Android phone in every 200 ms to nRF8001. But sometimes I found there is a 50 ms or 100 ms delay. It looks like nRF8001 spending some time in...
Hello,
I'm starting a new nRF51 project on mbed for a custom board. I wish to know what is the "cleanest" way to define pinout (what file to edit) ?
Thank you
I have enabled data ready interrupt bit and also enabled the fifo bit and also enabled gyro_fifo and accel_fifo bits in mpu6050 so that when data ready interrupt occurs the...
Hi,
it happened that we have some hardware boards populated with older chips rev. QFAACA and some with newer rev. QFAAG0 but we need to share same software. As I read newer...
by set a char with BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS, means it can't be read and write, if so, why not remove the char?
any reason behind BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS...

Hi!
I wonder what is the GPIOs nominal voltage level when I'm using the internal DC/DC converter?
