Hi,
I'm interfacing a nrf51822 and a H8/3294. My question is how much can I drain a the txd pin of the H8/3294. That means my question isn't really about nrf51822.
In documentation...
Hi,
On the 3.30 of nRF52832_Rev_1_Errata_v1.5.pdf, the sleep current with LFXO active is 0.5μA higher.
I am using a nRF52832 module with the low frequency crystal oscillator...
Hi,
I'm using nRF52832 on SDK V12.2. I add the connection params in the conn_params_init:
static void conn_params_init(void){
uint32_t err_code;

Hello, I am trying to follow the instruction for a 2way communication between nRF chip and the client device (cell phone). Although my chip is nRF51422/ PCA10028, I have found...
hi all:
Recently, I use nrf51822 as a central to connect some older sensor, but the ble chip of the older sensor did not use nordic, so I have this problem. I develop the...
