I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...
Hello,
I have this code
if (NRF_SUCCESS!=nrf_drv_twi_tx(&m_twi,devAddr,®Addr,1,true))
