Looking to hire an ANT+ developer (software only) for nRF52840/nrf54L

Hello all,

I am looking to hire a developer experienced with ANT+ together with BLE and the nRF52840 SoC, possibly the nrf54L10.

I am looking for the coding for the radio (ANT+/BLE) part and its interaction with the hardware (GPIO, ADC, PWM, etc.). I have experience with the design and testing of the actual final hardware - such as PCB design and manufacturing, Mosfet switches, LED drivers, etc. and I can test using the official Nordic DKs and my PCBs. I really need help with the code. All documentation, ANT+ simulation tools, etc. are available.

The project will require:

  • A master (remote button) - nRf54L preferred (for maximum battery life)
  • A slave (device) - nrf52840/nRF54L: (large on board battery so standby time is secondary)
  • Incorporate the ANT+ LGT device profile (ANT shared channels)
  • Concurrently running with BLE
  • Preferably using Zephyr, rather than the SDK5, though as ANT+ is now kinda frozen in time, older toolchain experience is also welcome and if it can result in a working code.
  • Bonus: Possibility to update firmware via BLE (or USB)

Project timelines - JAN2027 for a working V1 (TBD)

As ANT+ membership ended in JUL2025, so did the direct support from Garmin, therefore actual experience with ANT+ is a major plus (as it requires incorporating an ANT+ device profile).

For full details including your applicable hourly/project rate, please get in touch directly here or via (https://custompurple.com/contact/). Feel free to forward this to somebody that might be interested.

If this is not the correct place, please move to the appropriate forum.

Thanks in advance for any insights!

-Nikola
