I'm periodically polling a TWI sensor with a blocking call, as in
ret_code_t err_code;
m_xfer_done = false;
err_code = nrf_drv_twi_tx(&i2c, address, subAddress, 1,...
My external application processor UART, every 5 ms @ 19.2 KBPS transmits a byte to UART RCV of NRF8001, which needs to convert this to BLE and then transmit to a cell phone...
Hello All,
I am working on nrf52832 and i designing the custom board for the same for my application , which all pins i need to select as programming pins to dump the code...
I'm trying to figure out why "some" (as in not all of them) Android Devices drop my Bluetooth Low Energy connection (to an NRF52 which I don't think is the problem) after...
I'm trying the example border router using 2 x nRF52840 boards one with CLI and the other with NCP connected to a PI. I can get ipv6 addresses and get them to ping each other...
Hi, I am trying to control an Omnivision Camera module using the nRF51822 EK. The module uses their proprietary SCCB protocol, which is very similar to I2C. However, there...
I am now using 52832 to do a project, need to send a BLE broadcast package first, and then start scan, what examples can I refer to?
Attachment is my TX/RX process，and...
Hello,
I always observe 4.0xxV from the li-po battery attached after when thingy52 stopped charging.
I think this problem maybe because of output current from the battery...
On our project we're using a Raspberry Pi 3 compute module with custom hardware and 2x nRF51 SoC running HCI from Zephyr.
We'll be delivering more than 150 of those devices...
Hello! Can I use one of the gpio pin as power source directly for other MC on my board (hx711 - ADC with current consumption in normal mode 1.5ma (from datasheet)). I understand...
