I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...

In nRF5 SDK 12.1.0 a bug was fixed in nrf_drv_wdt_init(). Watchdog timeout could not be larger than 131 seconds because of (x * 32768) multiplication before. This bug is again...
In the spec it says that the typical ramp up time is 140us (or 40us in fast mode). But there is no details on maximum or minimum. What is the true tolerance on this value...
We are building a simple project, let 51822 connect the mobile, once per second. We found that the Tx power of 51822 is getting weaker and weaker (view the voltage over a...
I have a nrf51 dongle and would like to use PWM on 3 pins.
Managed to get it working on pins 15 and 16, but somehow pins from 17 to 20 just don't work.
For example: I set...
Hi,
I have two nrf52840 boards and I am using the ble_app_att_mtu_throughput test app. The tests seem to be working OK, but I am not getting the throughput I was expecting...
When performing flash operations, i.e. via FDS or FSTORAGE, etc. - will GPIOTE events be captured and 'queued' until the CPU is no longer halted?
Said another way:
