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...
