Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hi,
Does Nordic Semiconductor provide any resources (codes, macros, documents) for work with IAR or Keil's simulator to fully simulate nRF51822's peripherals?
Thanks...
Hi,
I do:
err_code = ble_bondmngr_bonded_centrals_delete();
APP_ERROR_CHECK(err_code);
till now all is ok.
But when I do:

Hi
I've a reproducable behavior i'm not able to explain. I'm using the softdevice S110 6.0 on a nRF51822.
The firmware implements some BLE profiles and uses TWI Master...
Is there a way to map external memory (SPI connected) to force the app to start execution from there ?
If not feasable , there is a way to transfer the execution from internal...
I have a 51422 board design and I just got Ant-FS working with our firmware so I can now download data from an external SPI flash to a desktop application.
I want to be...
Hello:
I am using NRF51822 to design somethings. And I want to use interrupt send method instead of polling send method.
NRF51822's UART0 provides TXDRDY interrupt. After...
Hi,
I have tested the nRF Toolbox proximity application using nrf51822 evaluation kit and with nexus4 smartphone it is working fine. Now my question is, is it possible to...
Hi
I am trying to overcome the problem that I have confronted, I have no buttons to delete bonds. So instead of deleteing this is what I did.
I modified the bondmanager...
I am developing hid_mouse . When I connect Android once and ubond hid_mouse I must set bluetooth off and on again to connect ble device otherwise it will connect again to...
Hi,
I am trying to set a value in the NRF_POWER->GPREGRET when softdevice is running, but it doesn't work. I don't get any error, but the value is always 3 and not 1 like...
