How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
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...
I need to send a long (let's say 10Kb) notification from Bluez 5.37 on my Linux device to a mobile phone.
My implementation is based on src/shared/gatt-server.c .

Hi,
I have put in my chip (nrf51422):
-1 softDevice s110 8.0.0;
-2 application (hrm_whit_dfu);
My problem is:
when i send characteristic to start advertising the board...
Hi everyone,
I am new to nRf series and have just started to use the nRF51 Development kit(nRF51422). I am using the s130 softdevice and I have seen that the sofdevice supports...
I'm trying to test out pin change interrupts using the PCA10028 dev board. I'm using two buttons to turn off and on an LED. The code below is only generating events from button1...
I have a custom board designed which implements a Arduino Micro (ATmega32U4) and an nRF8001 chip based upon Richard Clarks' nRF8001 breakout . The Arduino FW uses a slightly...
Hi.
Is it possible to enable the encryption of data which corresponds to the particular characteristics? i tried with BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM, for setting the...
Hi,
how is the new nrf_drv_twi supposed to be used for reading registers?
The sequence for that is pretty much industry standard:
> Device address
< Ack
> 0x00 (register...
I'm running the ble_hrs example provided on my nRF52 board. The thing is, I'm unable search my device using both nRF Master Control Panel and normal Bluetooth connection from...
I am using a central S130 softdevice in an nRF51822. I connect to a peripheral using sd_ble_gap_connect(&m_peripheral_address, &m_scan_param, &m_connection_param) . If it...
I am trying to provide a custom peripheral service with a 128-bit UUID in an nRF51822. I would like to use two bytes of the UUID to encode a piece of information unique to...
Hello,
am I right to assume that if sd_ble_gattc_write returns anything other than SUCCESS, then the packet was not queued?
Is this also true for BLE_GATTC_EVT_WRITE_RSP...
Hey guys,
I have a little problem on a new board comunicating with a MPU9250 sensor.
Chip version is nrf52832-QFAA-BA
GPIO PINS Used P0.20 (SDA) and P0.21 (SCL)...
The S332 v0.6 has been released and it is supposed to be compatible with SDK11. My concern is that in the release notes of SDK 11, it says "Temporarily removed support for...
I tried the above example but it hangs here:
while (ser_sd_transport_is_busy());
Not sure why, I'm using GDB to step thru code, and it appears always busy...
Is there...
