Hello! I am trying to prototype a DFU solution that works well for our application. We want to build a network with both normal Mesh devices and with friend nodes (once that...
Hi,
for my PCB, i'm using an NRF52832 as SPI slave, i send an array of 4 bytes {0xA5,0x00,0x01,ff}, but my SPI master receives always a byte (0xff) before 0xA5.
this...
Hello everyone
I have kind of a basic question.
I'm not sure how to manually disconnect from a ble connection. I'm using the ble_app_uart and ble_app_uart_c examples from...
Hey all,
We’re trying to figure out the best way of keeping our nRF52 (or 51) based design in the lowest power mode possible while sitting in inventory.
Currently, our...
Greetings,
I have 12 sensors each of which is located on an nRF52832 board. I need to collect the sensor data at 50Hz (10 bytes for each sensor).
For some reason I can...
This one is throwing me for a loop.
We just did a small build of 40 devices based around the nRF52832. 1 device out of those 40 is behaving very strangely. When the device...
Hi Sir
I want change the power transmission level for measuring the RSSI values for different configuration from -40DB to 4DB. for that i configure the radio. But it is...

Hello,
I am using the NRF51822 in a low power application and need to transfer the data from the PCB (with the NRF) to the PC over Bluetooth. I need the biggest possible...
Hi,
I would like to know if there is any reason that tx_power is limited to +4dBm in the Mesh examples. I am using an nrf52840 and it is capable of +8dBm. Would it increase...
I am starting afresh, and have only just downloaded & installed Keil v5.25, nRF SDK v15.0.0, and nRFgo Studio v1.21.2.10
So everything should be "latest" and "up-to-date...
