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...
I'm writing my own BLE discovery routine for S140. I'm finding that after I call sd_ble_gattc_descriptors_discover(), BLE_GATTC_EVT_DESC_DISC_RSP is passing attributes that...
Hi,
I just wanted to report that there is an issue with the solution suggested in this thread . Even when you manually manage double buffers outside the ble_advertising...
Dear all, I started nRF52840 development. Using this module, I'm going to use BLE and USB connection.
I have nRF52832 module, which sends BLE data by 1.28Mbps. I'm going...
Hello all,
if we design a AoA receiver based on the nRF52811 and our own antenna array, will it be able to locate beacons using Bluetooth 5.0 communication?
Kind regards...
We intend to connect an A-D converter to GPIO lines in SPI mode. The ADC generates a done pulse that is positive 3.3V and 56ns to 64ns wide.
Looking at v1.1 datasheet...
Hello,
During application development I've got SoftDevice fault PC: 0x000251BA. It happens always just after start `FDS Garbage Collector`, so I expect that can be related...
Hello. I work with two board nRF52832. One of them is a server, which has rx/tx characteristic, the second acts as a client. In both projects used BLE NUS.
When client NRF_SDH_BLE_GATT_MAX_MTU_SIZE...

What are the MIPs of nRF52832 with S132 softdevice enabled? Also, changing the softdevice to S332 will affect the MIPs? Regarding S132 and S332 softdevices, they are all same...
I have a custom PCBA running my development firmware. When I turn everything off (meaning no peripherals are active - most chips are in sleep mode or de-powered; BLE disconnected...
Hi
Can I use app_timer with APP_TIMER_CONFIG_USE_SCHEDULER set to 1 when using task manager?
Setting APP_TIMER_CONFIG_USE_SCHEDULER to 0 causes the timer to fire, but...
Hi,
I am using SDK 15.3.0 for nRF52840.
We don't want to use peer manager and id manager as we don't need bonding.
We added the remote device with public address type...
