I'm using SDK V11.0 with SD130 v2.0.1
This is the scenario...
Hi,
I used the code ble_app_uart_c on board 10028 as a base for my custom board.
My board is nrf51822 QFAA based so I changed all occurances of nrf51422 to nrf51822...
Hello,
We are trying to communicate to this board ( www.adafruit.com/.../1697 ) that has nRF8001 at its core.
Unfortunately, our TX is only able to output BLE 4.2

I'm running on nRF51822, SDK 8 (not totally sure, I inherited the project), SD130 and mbed.
I've tried and failed with my own code to use pstorage.
I'm now trying a...
Hi. I'm using nRF51822AC, SDK12.2.0, S130.
The size of "s130_nrf51_2.0.1_softdevice.hex" in SDK is almost 300KB.
But chip's flash mem size is just 256KB. It's bigger than...
How is it used? And why to use it?
static nrf_saadc_value_t m_buffer_pool[2][SAMPLES_IN_BUFFER];
instead of
static nrf_saadc_value_t m_buffer[SAMPLES_IN_BUFFER];

and ...
This should not be a sudden my PCA10040.
Jlink are probably going to have failed.
It does not appear in the USB Jlink to appear as Atmel.
Is there a way to recover...
