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...
Hi,
In the registery definition of nRF52840 it is stated for PSEL.TXD:
Reg ID: A -> from bit 0 til 4 for Pin selection
Reg ID: B -> bit 5 for Port number
In this case...
I am looking into interfacing a SD card to the nRF52840. I have used the FatFS example and that is working ok with SPI. Then I have looked at the QSPI example and that also...
Hello,
I am using sdk 12.2 and nrf52 dk.
I am storing some data in flash using ( sd_flash_write((uint32_t*)0x4F800,m_deadbeef, sizeof(m_deadbeef));) and I am able...
Hi
