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...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi all ...
My product uses multiple BLE peripherals (Simblee by RF Digital) communicating with a common BLE central to time events detected via sensors on the different...
Hi,
The situation:
I was able to successfully receive known packets from a device running gzp_device_dynamic_pairing, from, the host running the gzp_host_dynamic_pairing...
So the nRF51822 has one 32 bit, two 16 bit timers and two Real Time Counters.
What is the difference in a timer and counter? The timer API seems to hard link RTC1...
Hi,
In my project I am using nrfutil.exe tool to create a .zip by using the following command
nrfutil.exe dfu genpkg j1.zip --application application_nrf51822_xxac.bin...
I'm running into a weird problem where there is a long delay that is variable between calling ble_conn_params_change_conn_params() and receiving the BLE_GAP_EVT_CONN_PARAM_UPDATE...
Hello,
I've got a problem with my nRF51 DK. When I attach it to the USB port the drive doesn't appear on Windows explorer and green diode doesn't flash too.
I've been...
By design, the TI LP55231 LED driver IC will fail the TWI write of the reset register (0x3D). It's necessary to reset the IC in an edge use case. I'm using the nRF51822 HW...
Hi,
I want to write a characteristic, the value size is fixed, for example the size is 4 bytes. When I try to wirte 6 bytes from the client, the first 4 bytes is writed succesfully...
Hi all,
I have the nRF52 DK programming consistently without any trouble both on Kiel and using the nRFgo Studio.
My problems arise when I connect a 3rd party module...
Hi,
im trying to set up 3 PWMs for simulating a RGB LED with the 3 leds on the nrf52-dk.
I need the following behavior:
pushing on a button increases the width of the...
Hi,
I have implemented a custom application(Lets name that file app.hex) which works and sends the data to phone via BLE on my nrf51822 DK. I am using the s110 v8 softdevice...
Due to some constraints in the manufacturing process of my product, there is substantial mechanical variation in the BLE antenna. I can constrain this variation to a degree...
Hi,
I am trying to program MDBT40 with Jlink and having some problems.
Here is the scenario:
I have two versions of the MDBT40. One that I took off a BLE NANO (RedBear...
