Hello,

Some news !
i buy a Jlink, and success in erase my nrf52832 with nrf prog, using method of berkseo.

Next i try to upload a basic sketch (blink) :

#define MY_RADIO_NRF5_ESB
#include <nrf.h>
#include <MySensors.h>

void setup() {
Serial.begin(9600);
hwPinMode(LED_BUILTIN,OUTPUT_H0H1);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

I have this :

I think its good, but when i put a led with a resistance on P0.08, nothing :(

could you help me more ?

LED_BUILTIN corresponds to po17

I thought I mastered nrf5 platform bit it looks I am not.
I have a PCB where i2c sensor is hardwired to po30 and po31 of nrf52832.
What changes I have to make in MyBoardNRF5.cpp?
Shall I bring lines 28/29 that have "A4" and "A5" in their desciption to 30th and 31st position in the list?

@ileneken3 have you returned the jumpers back?

@omemanti said in [nRF5 action!]Maybe that's the €3 solution for unlocking.

BMP is enough to unlock. BluePill costs ca. €2 and it's easily convertable to BMP

@mr_red said in nRF5 action!:

Is there any way to do this over the programmer?

Not in Arduino. In KEIL you can use RTT (pretty cool stuff, debug via SWD)
But if you just want to decrease a number of programmers, you can use Black Magic Probe, made from BluePill ($2 at Ali). It is 2-in-1 SWD and USB-UART converter on one PCB

Can you pls. upload the design files?

@rozpruwacz said in my first nrf5 ... NRF51/NRF52 which is better for MySensors ?:

So smd modules are no good for me

If so, your only choice is nrf52DK. Solid investment given you get jlink programmer with it

how do you guys solder nrf52840 modules without reflow oven?
they have many pads at the bottom

@hugob said in my first nrf5 ... NRF51/NRF52 which is better for MySensors ?:

• The programmer on the Arduino IDE is not working for me ("No J-Link" error, while there is a J-Link interface available), so I export a HEX fle form Arduino IDE and program the board with the nRFConnect tool from Nordic.

if read sandeep's notes on Githun, you'll find you have to replace the driver with Zaddig but then Jlink will stop functioning in Keil.
That's why I use BMP for Arduino-style programming as it has its own drivers and do not ruin jlink installation

@rozpruwacz I would strongly encourage you do start with nrf52832 ebyte mosule coupled with Nevrdie's breakout board. It is a) proven b) cheap c) breadboard friendly

@omemanti that's strange, I use the methos regularly and it worls fine.
Oh! Actually, sandeep's installation messes up Jlink drivers so they require reinstall for the method to work.
That's why I am using arduino nrf5 with BMP to completely separate Arduino from Jlink

@omemanti actually, all you need is to issue the following command:
nrfjprog.exe --recover

@speechsupply this thread is golden. I was so empowered that was able to easily switch to nRF SDK and to start producing (semi) commercial BLE-ANT device

@neverdie I am afraid it still relies on Softdevice

@neverdie what are potential advantages of micropython?

@neverdie I've setup the bootloader for my BT project and I confirm its much easier than it looks.
Can it be used for MySensors? For BT, I create a hex file in Keil and then upload it via nrftoolbox app.
Can the same procedure be used with MySensors? OTA needs Softdevice and Softdevice is not compatible with MySensors

Guys, remind me pls: is CR2450 enough for the nrf52 Ebyte module acting as a Mysensors node?
Is it capable to handle tx current spikes?
Energizer datasheet states 9ma as max curent pulse. Is it sufficient?

@nca78 said in SMD Reflow Oven / PID:

small 10*10cm hotplate

interesting. Do you use an ordinary kitchen hotplate?

@neverdie c'mon, you don't need any special syringe. Ordinary BD will do
Regarding the motor operated one, I actually printed out a full set of 3d parts for the motor oerated syringe but never assembled as there is no need.
If I ever decide to automate the process, I'll make an air driven station with 2 valves. Mechanic solder syringes are supposed to be used with this type of dispensers.

@neverdie yes, although I use the one in small cans and reload small amount into 1 ml syringe (with proper gauge needle!)
