I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
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...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hi!
I have noticed strange problem with one of GPIOs - P0.15. We have tested 50 devices based on nRF52832 and 3 of them have problem with P0.15 after few days.
P0.15...
The default I2C address of my sensor is 0x29 (7-bit).
If the least significant bit is low (0x52) the message is a master write to the slave. If the lsb is set (0x53) then...
I'm using SDK 12.2.0 with softdevice S130 V2.0.1 and want to use TWI.
Using the ble_beacon example I added the twi code from twi_sensor.
Shortly after calling TWI_Init(...
Hi,
during normal operation, my device shows a power consumption of 4.7mA.
Normal operation is:
accelerometer (lis2dh) detects a shake and wakes up the nrf51 via...
Hii ,
i am using customized board (chip : BT832).
err_code = sd_softdevice_enable(clock_source, softdevice_assertion_handler); hangs. it took some delay and after that...
Hi all,
I have seen a pair of questions ( this and this ) that I think have something to do with this, but didn't find a solution.
I have a custom board with a button...
I want to have an application similar to UART in the SDK example, with multiple peripherals.
I tried to modified existing UART example, but cannot make the central node...
I want to add the nrf52832 to my customized board and I am studing the possibilities for flashing it once that is located on the board. Is it possible to flash trhough the...
I have a board with some LEDs that are driven in the same way as with the nRF51 DK board (i.e. there is a resistor in series with the LED and you drive the pin low to turn...
In our testing we encounter some devices (Centrals with nrf52832), where the peer manager event PM_EVT_BONDED_PEER_CONNECTED contains a invalid peer id 0x4000 (allowed values...
I have a device the uses MSP430f169 and CC2500 RF controller for communication I need to replace the CC2500 RF controller with nRF51422 device.
As I understand an nRF51422...
Hi,
I develop application on MBED platform with NRF52-DK. I figure out that pin "logic" on this board is interchanged. For example. I have LED connected to some pin. When...
Hello,
on my custom board I am trying to use pin P0.09 and P0.010 for interrupt-purposes. So I integrated the necessary adjustments as mentioned in this topic here , which...
Hi,
I develop application using BLE.
In my scenario two NRF52832 operate in two different roles (Client and Server).
I have ready to run app (as server) and can communicate...
Hi,
When I call nrf_drv_spi_transfer to transfer 250 bytes in non-blocking mode, it takes 1.1ms. Is this normal? Any workaround? If it is normal then I have to split my...
