Arduino BLE Library

Development Boards Artemis

Hi,

I have used ArduinoBLE library version 1.1.3 which is the latest one. I get the error message as below when compiled. I have also installed the extension for Artemis boards.

WARNING: library ArduinoBLE claims to run on samd, megaavr, mbed architecture(s) and may be incompatible with your current board which runs on apollo3 architecture(s).

Error compiling for board SparkFun Artemis Thing Plus.

Do you use the Sparkfun library 2.0.2 or the older 1.2 version?

I experienced same compile errors when trying to build LED example from ArduinoBLE lib for sparkfun artemis micromod. What “Sparkfun library 2.0.2” ?? Does sparkfun have example BLE sketch for artemis micromod? ArduinoBLE lib is v1.1.3

With the release of Sparkfun 2.0.0 you need to add a different jason file to the Arduino IDE to get Sparkfun library version (now) 2.0.2 which supports ArduinoBLE (else you will have version 1.2, which does NOT support ArduinoBLE and cause this error message) See https://learn.sparkfun.com/tutorials/ar … rduino-ide

I added new json file and installed 2.0.2 with boards manager. I could compile the BLE lib LED example, but upload failed on 1.8.12 and on 1.8.13 … and I couldn’t upload any sketch !!

I reverted back to 1.2.1 for apollo3 and i still can’t upload ANY sketch to artemis micromod board !

Artemis SVL Bootloader

Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader.

dang

using SVL ttyUSB0 @115200

6

use the Ambiq Secure Bootloader the SVL is Out of Order…

7

i couldn’t get BLE LED example to upload with ambiq (3 tries, upload fails) and 2.0.2. I removed apollo3 json and reverted to 1.2.1 with ambiq and I can now upload my old sketches …

so what is recommend to get BLE LED example to work? 1.8.12 only ? ambiq (baud doesn’t matter?) i’m using Arduino’s latest BLE lib. i notice sparkfun has a fork of that lib, but it didn’t help.

It works 1.8.13 with 2.02 on Artemis Nano. One other thing to try with that configuration is to:

Tools | Programmer: “Ambiq Secure Bootloader”

Tools | Burn Bootloader

That re-writes the Ambiq Secure Bootloader which can get screwed up in some scenarios.

Now try upload with Ambiq Secure Bootloader.

I made some progress with 2.0.2, ambiq, and 1.8.13 (seems to upload better when USB is not through a hub). LED example loaded and ran, maybe, nothing printed on serial monitor, and not sure if my iphone is seeing a BLE device. I notice that enableBurstMode() (for 96mhz) is not defined in 2.0.2 — is there another way for 96 mhz.

for Nano had to comment out line in file to get Serial.print to work:

Fix for Nano not printing with Serial.print

in file: 2.02/variants/SFE_ARTEMIS_NANO/variant.cpp

comment out line: Serial1(SERIAL1_TX, SERIAL1_RX);

Edge2 variant.cpp does not have this line and prints fine. 115200 works better than 9600 which looses char’s.

Don’t know about your board and what kind of UART chip it has…but worth a try if your variant has that line for Serial.print prob’s.

11

just checked, that line is not present in your board’s varian.cpp file…so…maybe you need to add it?

should look like:

UART Serial1(SERIAL1_TX, SERIAL1_RX);

Does sparkfun have example BLE sketch for artemis micromod?
